I-580 at Foothill Road Interchange Project Now Underway

The City of Pleasanton Engineering Division reports that road construction to modify the I-580 interchange at Foothill Road has begun. The freeway on and off ramps at Foothill Road will occasionally be temporarily closed to traffic between the hours of 10:00 p.m. and 5:00 a.m. for night work. Ramp closure dates and times will be posted in advance at the ramp entrances.

The project is expected to improve operation and safety and will reconfigure the interchange by replacing the direct eastbound to southbound, and eastbound to northbound off ramp loop connections with a “T” style intersection at Foothill Road, just south of the I-580 interchange. The construction work is expected to take one year to complete and the project is funded by City Transportation Improvement Development fees, Measure B, Tri-Valley Transportation Development fees, and a Congestion Mitigation and Air Quality (CMAQ) grant.

This intersection will be signalized and will significantly improve interchange safety by removing two problematic weaving locations caused by the existing off ramp connections. The eastbound off ramp will terminate at Foothill Road and include eastbound left and right turn lanes. The project will also relieve the weaving concerns at the intersection of Foothill Road and Canyon Way.
