Information provided by CalTrans:

Hercules – On Monday, April 18, and Tuesday, April 19, from 7:00 a.m. to 2 p.m., one-direction traffic control will be in effect on the segment of Willow Avenue that runs beneath Interstate 80 in Hercules. The eastbound Interstate 80 Willow off-ramp will also be closed on Monday, April 18 from 6 a.m. to 2 p.m., and Monday night, from 8 p.m. to 2 p.m., Tuesday afternoon.

During the Willow Avenue closures, traffic will be reduced to one lane. Flaggers will guide traffic.
