【明報專訊】省府昨日公布取代馬西隧道(George Massey Tunnel)的3.3公里全新10線道大橋計劃,打造一個卑詩史上最大、備有單車線的大橋,同時還會拓寬連接新橋的99號公路。新橋造價高達35億元,將會以收取過橋費的方式回收成本,預料需要至2022年才能通車。

 

 

卑詩運輸及基建廳長斯頓(Todd Stone)表示,用來取代馬西隧道的大橋預計耗資35億元。新橋全長3.3公里,將會是卑詩省史上最大的橋樑。橋面將會有10線道,其中2線為公共運輸及汽車共乘專用道(HOV Lane)。另外還會有單車及行人專用道,同時也會在橋中央預留空間給未來可能增設的捷運系統。

 

斯頓透露,大橋將會比照曼港橋(Port Mann Bridge)收取過橋費,以「用者付費」的方式回收建築成本。但他並沒有公布過橋費多少,僅稱目前正在向聯邦政府申請撥款,未來將會按照渥京撥款的數額,決定是否用來降低過橋費率,抑或是縮短貸款償還款期。

 

根據省府的規劃,連接99號公路的新橋,將會在17A公路、史蒂夫斯頓公路(Steveston Hwy.)、西敏公路(Westminster Hwy.)等三個地點鋪設全新的交流道。為了配合新橋的10線道寬度,99號公路從三角洲91號公路至列治文橋港路(Bridgeport Rd.)長達24公里的路段將全面拓寬,增設兩條公共運輸及汽車共乘專用道。

 

斯頓預計,新橋預每天可為1萬名公共運輸乘客,以及8萬部汽車的司機及乘客省下25至35分鐘時間,增設的行車線也能減少35%的交通意外。雖然99號公路北端的橡樹橋(Oak Bridge)未有擴建,但他稱在新橋完工後,預計橡樹橋的車流不會有明顯增加,而交通阻塞是否繼續存在,仍取決於西70街十字路口的交通燈。

 

目前的4線道馬西隧道是在1959年通車,隧道結構位於菲沙河牀並以石塊覆蓋,但已經不符合現代防震標準,一旦發生地震,很可能會出現坍塌及水浸。而狹窄的4線道在人口及汽車增加下已不敷使用,只要發生交通意外,一定會造成三角洲及列治文兩市嚴重交通阻塞。

 

取代馬西隧道的大橋計劃是在前年宣佈,但今年稍早省府評估的造價僅為30億元。昨日增加的5億元費用,除了建築成本上升外,還加上周邊道路擴建,以及關閉原有馬西隧道的相關開支。

 

新橋目前已經進入最終諮詢階段,預計將會在2017年初動工,2022年完工通車,但省府尚未確認大橋的名稱。根據省府的統計,目前通過馬西隧道的北向車流,有59%是前往列治文,40%是前往溫哥華。

B.C.’s transportation minister says replacing the aging George Massey Tunnel with a 10-lane toll bridge will drastically reduce congestion on the busy commuter route.

 

Todd Stone said the three-kilometre bridge over the Fraser River will cost $3.5-billion, up $500-million from initial estimates.

 

The bridge will include an HOV lane in each direction, as well as a cycling lane and pedestrian access.

 

Construction will begin in 2017 and isn't expected to be completed until 2022.

 

The estimated toll costs to drivers have not been announced, but Stone said they would likely be comparable to those of the Port Mann Bridge.

 

Stone promised that the new bridge would reduce commute times drastically.

 

"The new bridge to replace the Massey Tunnel will improve highway safety, reduce greenhouse gas emissions from unnecessary idling, and save rush-hour commuters up to 30 minutes a day," said Stone.

 

"This will be the largest bridge ever built in B.C. When completed, it will address what is now the worst traffic bottleneck in the province and bring travel time reliability to one of our most important transportation corridors, serving national, provincial and regional economies."

 

The additional lanes will reduce collisions by 35 per cent because it will be safer to merge, said Stone.

 

The province says the current tunnel no longer meets seismic safety requirements, and many of its major components only have a decade of useful life left before they need to replaced.

 

The new bridge will accompany improvements on Highway 99, including new interchanges in Richmond and Delta.

Currently, more than 80,000 vehicles use the tunnel each day.
