The existing bridge has only seven lanes, some of which are narrower than the current standard width of 12 feet. The new bridge will have eight 12-foot-wide lanes. The wide shoulders of the new crossing will greatly reduce the traffic impact of disabled vehicles and accidents, which can cause massive tie-ups on the existing bridge. The incline over the main span will not be as steep, allowing large trucks to maintain consistent speed and reduce engine and braking noise. There will also be gently banked curves to help smooth traffic flow and reduce accidents as well as a cashless tolling system to eliminate the need for drivers to slow down or stop at a toll plaza. In addition, the new bridge is being built with the structural capacity to handle commuter rail, light rail, or bus rapid transit.
