The Holly Street-Highway 101 interchange is going to get some traffic relief thanks to an approved allocation of $3 million from the San Mateo County Transportation Authority on Oct. 4.
The interchange modifications project was the seventh most heavily funded project of the 27 applications from various cities and agencies in the count. The current L-10 cloverleaf interchange will convert to a Type L-9 partial cloverleaf interchange by eliminating the southwest and northeast quadrant ramps and realigning diagonal on and off ramps. The northbound on-ramp will receive an additional one lane and one HOV lane and one lane will be added to the northbound off-ramp. There will also be a grade-separated bike-pedestrian bike path through the interchange.
The Transportation Authority ultimately awarded $82.7 million for 23 projects around San Mateo County.

“By programming funds for future projects we are building a ‘pipeline’ that will set the course for our capital improvement program for the next 25 years,” said Authority Chair Carole Groom.
