The Metropolitan Transportation Commission has announced that each of the original joints on the Richmond-San Rafael Bridge will be replaced with new joints.
The original 31 joints were installed in the mid-1950s.
To avoid cracking on the upper deck, the new joints will shrink and expand as the weather changes with a rubber seal, according to officials.
Crews will be working this week and they expect to have all joints replaced on the upper deck in July.
Crews will work through the night from 9 p.m. to 5 a.m. -- Lane closures will occur most nights.
