Construction Update – Week of November 1st
Daytime Work in the City of San Mateo - Retaining Wall Work Delayed
Retaining wall work in the City of San Mateo, initially scheduled to begin November 4, has been delayed until further notice. Once work begins, construction crews will install the foundations of a retaining wall on southbound U.S. 101, south of the on-ramp from East Hillsdale Boulevard, requiring the intermittent use of a hydraulic hammer. Once initiated, this work is scheduled to take place from 1:00 PM to 9:00 PM and is anticipated to take place over 5 non-consecutive working days. The work may produce noise and vibration from the intermittent use of a hydraulic hammer as well as other common construction-related sounds such as backup alarms.
In addition, the closure of the following two southbound U.S. 101 on-ramps will be required for safety reasons: Eastbound East Hillsdale Boulevard to Southbound U.S. 101 On-Ramp, Westbound East Hillsdale Boulevard to Southbound U.S. 101 On-Ramp.

Expect minor construction activities to complete this section of sound wall in the coming weeks.
Upcoming Construction (North of Whipple Avenue): Construction activities in the coming weeks on U.S. 101 from Whipple Avenue (in Redwood City) to I-380 (in South San Francisco) will include: continued work on removed sound walls in the City of San Mateo; installing overhead signs, temporary concrete barriers, guardrails, temporary lighting, temporary ramp meters, and stormwater drainage systems; grading; paving; roadway excavation; demolishing concrete barrier; and other related construction activities.
