Express lanes – I-680 Walnut Creek to San Ramon Update November 2015


Summary

Structural work for the Cast in Drilled Hole (CIDH) pile sign foundations is now underway779 throughout the I-680 corridor between Walnut Creek and San Ramon. This is in conjunction with the on-going electrical work that is taking place on some city streets and I-680. Work will continue to occur during both day and night shifts. CIDH pile foundations provide deep support for structures that have the potential to shift. Crews drill deep shafts, reinforce them with steel cages, and then pour concrete to create strong foundations for the future overhead signage. The foundations will support the electronic signs that will provide information about the Express Lanes.

What to Expect

  • Intermittent nightly closures are ongoing in the northbound and southbound #1 and #2 lanes (lanes closest to the median). Construction crews are permitted to work on these lanes between the hours of 8 p.m. through 5 a.m., Monday through Thursday nights and 8 p.m. through 7 a.m. on Friday nights.
  • 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 will remain along the corridor to maintain a safe work zone.
  • Construction lighting will be present and directed away from residential areas.

Construction is a dynamic process and information is subject to change without notice. Work is subject to weather conditions. Please use caution while traveling through the construction zone.
