While the final design has yet to be determined, Pam Ryan, director of planning for the project, told the South Delta Probus Club last week that while the bridge will be built over the tunnel, all existing roadways will remain open during construction, including the River Road exit ramp.
The 10-lane bridge will be built to the same height as the Alex Fraser Bridge - 57 metres.
On the bridge there will be three lanes each way for regular traffic, one each way for transit, and one lane each way for slow moving vehicles. Rapid transit may be incorporated later on an additional bridge level. Pedestrian and cyclists will be accommodated, likely on a pathway outside the bridge roadway.
Ryan said that 60 per cent of traffic coming from south of the river is going into Richmond, not Vancouver, and daily traffic volumes on the Oak Street Bridge have declined.
The bridge construction will also include the widening of Highway 99 to extend the existing HOV/transit lane, as well as the replacement of the Steveston and Highway 17A interchanges.
