Caltrans and the Bay Area Toll Authority today issued the fourth of a weekly series of updates on the work underway to replace 31 joints on the westbound upper deck of the Richmond-San Rafael Bridge.
Construction crews have now replaced 22 of the 31 deck joints, and expect to finish work at six more locations this week, with the entire project on track for completion this July. Each of the original 1950-era joints is being replaced by a new joint that features a rubberized seal designed to shrink and expand with changing temperatures. This will prevent cracking of the surrounding concrete road deck.
To minimize impacts to commute traffic, joint replacement work is being done at night. Drivers can expect one lane of traffic to be closed most nights from 9 p.m. to 5 a.m. New steel plates have been installed at work locations. Drivers can pass over these plates at posted speeds. There is no need to slow down for these plates.
