Overview

A straight line from Kawasaki City on the Kanagawa Prefecture side to Kisarazu City on the Chiba Prefecture side in the central part of Tokyo Bay[3]Tie to and crossMotorway Oftoll roadBy the name of[4],Kawasaki Ukishima Junction (JCT)- Kisarazu Kaneda Interchange (IC) "Tokyo Bay Aqua Line", Kisarazu Kaneda IC- Kisarazu JCTThe area is called "Tokyo Bay Aqua-Line Access Road".Special Measures Law Concerning Construction of Tokyo Bay Crossing RoadNow, cross Tokyo Bay between Kawasaki City and Kisarazu CityGeneral national roadTheTrans-Tokyo Bay RoadIt is defined as, and also oldJapan Highway Public CorporationThe so-called private-sector method was embodied on the premise of paid management.Road lawAbove isGeneral highway 409It is designated as a route ofMotorwayIs specified in.

The total length of the entire Tokyo Bay Aqua-Line Road is 15.1Kilometers (km), of which, in the section of about 9.5 km on the Kawasaki side that crosses Tokyo BayTokyo Bay Aqua Tunnel[5] と 呼 ば れ るtunnel, In the section of about 4.4 km on the Kisarazu sideAqua Bridgeと 呼 ば れ るbridgeThere is[4][6][7].

The place where the tunnel and the bridge are directly connected isArtificial islandIsUmihotaru Parking Area (PA) is set up in both Kawasaki and Kisarazu directions within Umihotaru PA.U-turnIs possible[7]..Aqua BridgeJapanBridge of length (total length 4,384 m)[8], Tokyo Bay Aqua TunnelYamate tunnel-Kanetsu tunnel-Hida tunnelIt is the fourth longest tunnel in Japan after Japan (total length 4 m, as an undersea road tunnel).The best in the world[9][7]) Road tunnel[10]..In addition, the inside of the aqua tunnel is known for passing through the lowest altitude in Japan (60 m below sea level) among general national highways.[11].

Umihotaru PA, an artificial island in Kisarazu, has a width of 100 m, a total length of 650 m, and a five-story rest facility.[7]..On the other hand, Kawasaki Artificial Island "Kaze no Tou" is a circular artificial island with a diameter of 195 m, located in the middle of the aqua tunnel and ventilates the inside of the tunnel.[7].

1988In November, the jurisdiction division line of the police jurisdiction was set in the tunnel part between Kawasaki Artificial Island (Wind Tower) and Kisarazu Artificial Island (Umihotaru Parking Area), and the west side of the division line was set.Kanagawa Prefectural Police, On the east side of the dividing lineChiba Prefectural PoliceIs under the jurisdiction[12]. Also,1997In October, the relevant local governments, Chiba Prefecture, Tokyo Metropolitan Government, Kanagawa Prefecture, Kisarazu City, and Kawasaki City, agreed on the same as the jurisdiction division line and set the boundary line.[13]..In December of the same year, an agreement was made under the jurisdiction of the fire department, and the entire aqua bridge and the aqua tunnel up line were established.Kisarazu City Fire DepartmentBut on the aqua tunnel down lineKawasaki City Fire DepartmentWill be in charge[14]..On the Kisarazu artificial island, there is a garage for a dedicated fire engine with a low body that can run in the evacuation pit of the aqua tunnel.

In order to enhance the attractiveness of the night view spot, the pole-shaped lighting installed at intervals of 150 meters was removed.LED lightingConstruction of a total of 285 lights was started in November 2013 and completed in August 11.[15].

Construction

(I.e.とKisarazuThe aqua line connecting with is on the Kawasaki sideShield tunnel, The Kisarazu side has adopted a bridge.This structure was adopted after a major shift from the originally envisioned construction method and structure.

In the concept around 1971, both sides of the Kawasaki side and Kisarazu side had a bridge structure, and the central part was not a shield tunnel.Immersed tunnelWas to be[16]..The use of tunnels is a trade-off between ships and aircraft, which are the existing transportation over and over Tokyo Bay.

In other words, if a bridge structure is adopted in all sections, it will hinder the navigation of large vessels.That said, if you secure enough altitude to pass a large vessel on the bridge,Haneda airportWill be an obstacle to aircraft taking off and landing.Therefore, it was necessary to provide a tunnel part that would allow large vessels to navigate.[16].

Actually, two plans are included in this concept stage, while (Plan A) is based on the tunnel ventilation technology at that time, a 3 km submerged tunnel was constructed in the central part, and two artificial islands with embankment structure were used. It was connected to a bridge.On the other hand (Plan B), the point that only the central part is a submerged tunnel remains the same, but an artificial island for ventilation is also installed in the central part of the tunnel to connect two submerged tunnels and a total of 2 km is constructed as a tunnel structure. It was a plan.

Then, due to the superiority of construction costs, Plan A was examined in detail, and in 1975, the Ministry of Construction announced a plan to make the central part a tunnel structure, and after that, the project was investigated on the premise of Plan A. Around 1981, the plan was changed to a central part of 1 km in one submerged tunnel, reflecting the progress of ventilation technology, but the structure of plan A with one submerged tunnel in the central part did not change. ..

In 1985, the plan was changed from a structure with a submerged tunnel in the central part to a tunnel structure for all 10 km on the Kawasaki side, and a shield method for the tunnel construction method.The reason is that there are many vessels sailing on the Kawasaki side, and it is said that as many as 1 vessels actually pass through the planned construction site a day, but about 1,300% of the total is the planned bridge part on the Kawasaki side. Because I was focused[17]..In addition, it was said that if the Kawasaki side was changed from a bridge to a tunnel and the tunnel construction method including the central part was changed from the submerged construction method to the shield construction method, the impact on the sailing vessels during construction and after the start of service could be reduced.[17].

At the beginning of the concept, the shield method was still under development, and there were no cases where it was adopted only for small-diameter tunnels and for large-diameter undersea tunnels. This is because it has become feasible.Furthermore, in terms of construction costs, it was found that even if the Kawasaki side was changed to a tunnel structure, it would not be much different from building a bridge by spending the construction cost of substructure on soft ground.[17], The current structure has been adopted.

The shield tunnel (Tokyo Wan Aqua Tunnel) and the bridge (Aqua Bridge) are connected by a Kisarazu artificial island (Umihotaru PA) with a length of about 650 m and a width of about 100 m, and the bridge girder of the Aqua Bridge is near Umihotaru. It is high to secure the span that a ship with a total ton of 2,000 tons can navigate and to secure the clearness of the lower part of the girder.[7]..In addition, in order to improve earthquake resistance and running performance, multi-span continuation is being achieved, which is the largest number of 11 spans in Japan.[7].

The excavation of the Tokyo Wan Aqua Tunnel was carried out by a total of eight shield machines with an outer diameter of 3 m, which is the largest in the world and started from three locations: Ukishima, Kawasaki Artificial Island (Wind Tower), and Kisarazu Artificial Island.[7][18].

Kawasaki Artificial IslandIs a donut-shaped vertical hole base located in the middle of the tunnel, and was first constructed with Kisarazu Artificial Island to launch the shield machine.Kawasaki Artificial Island will also be used as a ventilation tower for tunnels after it is put into service, and at the center of it will be a facility that replaces exhaust gas with fresh air.Since ventilation is performed using the wind that blows in Tokyo Bay, the inclination of the ventilation tower is the result of aerodynamically calculating all the directions and strengths of the wind that change with the seasons.[19].

The material used for the structure of Kawasaki Artificial Island is one that does not diffusely reflect the radar waves emitted by airplanes taking off and landing at Haneda Airport.The ventilation tower of the tunnel is also installed on the Kawasaki side and functions as a ventilation port for Ukishima.The Ukishima ventilation port had a pyramid-shaped (square pyramid) decoration,Haneda airportWhen the D runway was put into service, the upper part of the ventilation port became an obstacle to the route, so in 2009, repair work was carried out to remove the upper 12 m.[20].

Since the cross section of the shield method is circular, there is a management road under the roadway of the Tokyo Bay Aqua Tunnel, where emergency vehicles pass.Optical fiberCommunication cables such as are installed.The lower part of this roadway also functions as an evacuation passage.(I.e.By increasing 0.1%, smoke is prevented from entering in the event of a fire, and it is possible to get off the road with a slope.[20][21]..There are evacuation exits (300 places in total on the upper and lower lines) every 66m on the roadway, and the evacuation passage is directly connected to the NEXCO East Nippon Iwatsuki Road Control Center.emergency phoneIs also installed[22].

The aqua line has four lanes for both the tunnel and the bridge, but it is being constructed with a structure that can be changed to six lanes in the future.In the Tokyo Bay Aqua Tunnel, preparation work has been done at the wellhead so that another tunnel for two lanes can be excavated in addition to the current up and down lines, and about 4 m behind the holiday parking lot of Umihotaru PA. In addition to the excavation of the tunnel, the wind tower has a structure to which a third tunnel can be connected.In addition, the Aqua Bridge has a structure that allows widening to add lanes to the outside.[20].

Effect of construction

With the opening of the Tokyo Bay Aqua-Line, the distance between Kisarazu and Kawasaki has been reduced from about 100 km to 30 km, and the time required has been reduced from about 90 minutes to about 30 minutes.[7]..The peninsula of the Chiba Boso area has been eased, contributing to the improvement of logistics efficiency in the Tokyo metropolitan area, the economic and industrial development of the Boso Peninsula, and mutual cultural exchange between the two banks.[7][4].

The total construction cost is about 1 billion yen, but the usage at the time of opening is much lower than the estimated traffic volume, and thatCost-effectivenessThere is criticism in terms of[23]..This is a tollhighwayBecause it is not incorporated into the national pool system and it is very expensive to redeem the Aqualine alone.[23], The upper sea of ​​a regular car costs 1 yen per km at the regular rate, which is also expensiveHonshu-Shikoku connecting roadSlightly lower.As a result, it is important for profitabilityproblemHowever, it has been pointed out that the original outlook for estimated traffic volume was unsuccessful.[24]..20 years after opening (2017), 64,000 vehicles a day in total on the upper and lower lines, that is, on two lanes on each side without a 2-hour break, 24secondIt was estimated that one car would pass by[23].

Regarding the setting of tolls, after several fare revisions, the regular car fare, which was 4,000 yen at the time of opening, has been reduced to 3,000 yen.Further back to 1997, before the opening of the Aqualine.consumption taxI was planning to raise the tax by 5% and pay 5,050 yen for a regular car, but at that timeMinister of ConstructionKamei ShizukaWith a single voice of the crane, the redemption period was extended from 30 years to 40 years and the price cut was decided.[Source required].

Of constructionthe purposeAs one ofTokyo Bay Ring RoadAnd also with the Ken-O Expressway3 ring roadResponsible for part of the outermost ring road ofShuto Expressway Wangan LineIt was expected to help alleviate traffic congestion,[25], Only 15KilometersDue to the high tolls on the road, there were no cars to switch to the Aqualine, and there were no noticeable results.[23].

But,Tateyama ExpresswayWith the opening of all lines from TokyoMinami BosoThe time required to complete the process has been reduced by about an hour.Also in April 1Metropolitan area central connecting expressway(Ken-o Expressway)Togane JCTIs open,Boso PeninsulaBy crossing the mountainsMobara-Isumi-gunな どSotoboThe time to reach the northern region has also been shortened.

On the other hand, the fare is relatively cheap for shoppers living in the Boso Peninsula.Express BusWill be leaked to Tokyo or Yokohama,Straw effectThe result of being promoted (Later),Kisarazu StationpreviousDepartment storeIsKisarazu Sogo,supermarketWithdrew one after another, and the shopping street in front of the stationShutter streetUnsold land for residential areas and industrial parks created in anticipation of the opening of the aqua lineLand priceCrashed, centered on Kisarazu cityTrade areaIt was a big blow to the economy2010 eraIt contributed to the long-term stagnation until the first half[26][27][28].

2009 years,Kensaku MoritaWas elected in the Chiba prefectural governor's election, promising that "the price will be reduced to 800 yen for ordinary cars" only for ETC wireless driving.The promise isAso CabinetIt was carried out after consultation with.The traffic volume on the Aqua Line has increased due to the reduction of tolls due to the social experiment. The average daily traffic volume was 1, but now it is 1.Chiba Prefecture estimated that the economic effect of reducing tolls would be 4 billion yen in two and a half years.[29].

In addition, workers commuting to the Keihin area are commuting to Kisarazu City and Kimitsu City one after another.movingAnd land prices soared, or in the suburbsoutlet mall,Shopping centerAre gradually expanding and recovering to the economic situation before the opening of Aqualine.[27][30].

History

The concept of the Tokyo Bay Crossing Road was in 1961 (Showa 36).Industry Planning CouncilAs stated in the 12th Recommendation "Crossbank of Tokyo Bay-As a Solution for Storm Surge and Traffic-" (announced on S36.7.20), the concept itself existed from that time, but 30 It is a road that was realized in 1997 (Heisei 9) after more than a year.[33].

Based on the Act on Special Measures Concerning Construction of Trans-Tokyo Bay Road, Tokyo Bay Cross-Road Co., Ltd., which was established jointly by the private sector, local public organizations, and Japan Highway Public Corporation, will construct and manage the road, and the Japan Highway Public Corporation will own the road. The project was carried out by a method of external adjustment[7]..Tokyo Bay Crossing Road Co., Ltd. is in charge of the construction work for the approximately 14.3 km section above the sea of ​​the Tokyo Bay Aqua-Line, and the Japan Highway Public Corporation is in charge of business adjustment, land acquisition, fishery compensation, and land in Kawasaki City and Kisarazu City. Responsible for the construction of the department[7].

In addition to the soft ground of the sludge layer, the seabed of Tokyo Bay is the first human being to face many technical problems due to the combination of adverse conditions as an undersea tunnel where earthquakes frequently occur.MonthReached the surfaceUnited States Federal Governmentof"Apollo project"Apollo program for civil engineering" was called by engineers.[34]..Approximately 46 tons of steel and 70 tons of cement were used for the construction, and the total construction cost reached approximately 1 trillion yen.[6].

Under the policy of switching from maintenance-oriented charges to usage-oriented chargesIsewangan ExpresswayThe charge level has been reduced to 108.1 yen / km, which is equivalent to[40]..However, in consideration of the debt repayment situation and the current situation that the ratio of ETC vehicles is increasing and the difference in toll collection cost is widening, it was decided to implement it for 10 years only for ETC.[41].

ETC ordinary car 800 yen will be continued at the same amount even after 8 when the consumption tax rate will be 2014%, assuming that Chiba Prefecture will continue to bear a part of the cost, and the financial resources will be 25 Allowed by supplementary budget[42].

Although it is reported that the discount period is 10 years[43][44], This was reported based on the implementation period of the above-mentioned usage-oriented fee level, and in the NEXCO press release, "for the time being"[41], In the business license, "until the date specified separately by East Nippon Expressway Company Limited"[45] It is said that the execution of necessary financial resources was renewed every year by consultation between the national government and Chiba prefecture.[46]

Chiba Prefecture has a policy of continuing assistance,2015In the initial budget plan of Chiba Prefecture, 5 million yen is recorded as a Tokyo Bay Aqua-Line rate discount project.[47]..The business continuity consultation between the national government and Chiba Prefecture was held every year, but from 2019 it was changed to a three-year consultation.[46].

Traffic volume

Traffic jam

At the beginning of the opening, due to the small amount of traffic due to the high tollsNatural trafficHowever, due to the gradual increase in traffic volume due to the measures to reduce tolls, it hits both ends of the Tokyo Bay Aqua Tunnel during peak periods such as commuting hours and Golden Week.Kawasaki Ukishima JunctionCongestion of about 1 km due to slowdown has become common on a daily basis near (up line) and Umihotaru PA entrance (down line).During the daytime on holidays, traffic jams may occur near the front of the branch due to waiting for warehousing at Umihotaru PA.In addition, because it is almost straight with the slopes of tunnels and connecting bridges, rear-end collisions and broken cars are likely to occur, and accident congestion due to lane restrictions may occur.

After 2012, when the traffic volume increased dramatically, the up line will be on weekends and holiday evenings.Kawasaki Ukishima JCTFrom the aqua access roadKisarazu JCTCongestion across the entire line began to occur frequently[51](Also on the parallel routes Keiyo Road and Higashi Kanto Road, there are many cases of traffic congestion during the same time period.[52]).
