While it took a half-century of traffic growth to require a bridge to replace the ferries crossing the Carquinez Strait between Benicia and Martinez, it took only a couple of decades for ballooning traffic on Interstates 680 and 780 to overwhelm the Benicia-Martinez Bridge, also known as the George Miller Jr. Bridge.

To accommodate the growth, as well as meet seismic safety standards, Caltrans has widened and seismically retrofitted the existing Benicia-Martinez Bridge. As part of the RM 1 program, BATA and Caltrans have completed a second parallel span that carries five lanes of northbound traffic. The second span opened to traffic on August 25, 2007 and is named in honor of Congressman George Miller, who is the son of late State Assemblymember and state Senator George Miller, Jr.

The original span is being converted to carry four lanes of southbound traffic as well as a new bicycle and pedestrian pathway. The reconfiguration of the original span is currently ahead of schedule with an estimated opening date of September 2009.

A new Benicia-Martinez Toll Plaza has been constructed and features Northern California's first open road tolling system, allowing FasTrak customers to travel through the toll plaza at 55mph.
