Traffic Advisory

Overnight Closures at I-580/680 Interchange in Dublin Tonight

All lanes of both southbound and northbound I-680 at the I-580 junction in Dublin will be closed tonight between 10 p.m. and 4:30  a.m., Caltrans officials have announced.

In addition, all lanes of westbound I-580 will be shut down at the same time.  Motorists traveling on either interstate will be detoured to a collector road adjacent to the main freeway;  they will not have to exit the freeway during this closure.

The closures are for striping and removal of temporary supports.

This work is part of an overall $59 million interchange reconstruction project to provide a direct 2-lane connector between south-bound I-680 and eastbound I-580, new southbound I-680 on/off-ramps at Dublin Blvd. and a new north-bound I-680 on-ramp at Dublin Blvd.

Electronic and fixed message signs have been posted in advance to advise motorists, who may experience minor traffic delays and inconvenience during this temporary closure.

Due to inclement weather, tonight's scheduled overnight freeway and ramp closures on Interstate 80 have been rescheduled for tomorrow night, April 12, for work on the City of Berkeley's bicycle/pedestrian overcrossing, which will span I-80 near University Avenue. All other work that was scheduled for earlier this week has been completed.

The closures are scheduled as follows, weather permitting, and are subject to change:

Thursday, April 12 to Friday, April 13

During the full freeway closure of eastbound I-80 early Friday morning, April 13, traffic will be detoured to the Ashby Avenue off-ramp, westbound on Ashby Avenue, northbound on San Pablo Avenue, then westbound on University Avenue, and then diverted back to eastbound I-80.

Al freeway lane and ramp closures and detour routes will be clearly marked to advise motorists. Traffic delays are expected, and motorists are advised to use alternate routes if possible.

The bicycle/pedestrian overcrossing will be a $4.5 million state-of-the-art steel arch structure that spans all lanes of I-80, connecting the City of Berkeley with its Marina. Construction of the bridge project, administered by the City of Berkeley, is expected to continue until Fall 2001.
