Construction crews continue to install cast in drilled hole (CIDH) pile sign foundations and sign posts throughout the I-680 corridor between Walnut Creek and San Ramon. Crews have completed 21 of the 31 piles. Crews also continue electrical work on some city streets and along I-680. Work occurs during both day and night shifts.
The sign posts will support the future placement of overhead toll system signs. The electrical system being installed on city streets and along I-680 will provide power to the toll system signs.
Intermittent and alternating nightly closures continue in the northbound and southbound directions in the lanes closest to the median and the lane closest to the shoulder. Approved construction work hours are: Monday through Thursday from 8 p.m – 5 a.m, Friday from 8 p.m. – 7 a.m.
- Construction crews will be present on some city streets near I-680 with temporary and minor pedestrian detours to maintain public safety.
- Temporary k-rail, construction signage and orange plastic fencing remains along the corridor to maintain a safe work zone.
- Construction lighting will be present and directed away from residential areas.
