Work Begins on Reconstruction of US 101 Broadway Interchange

Reconstruction of the Broadway Interchange on US 101 in Burlingame kicked off today with a ground breaking ceremony near the aged overpass. The awkward, complex interchange made crossing the freeway from Burlingame to the Bayshore Highway a challenge for residents and confusing for visitors. Originally constructed in 1947, the interchange is the oldest one in San Mateo County.

“If any interchange in the county needed improvement, this is the one,” said Karyl Matsumoto, chair of the San Mateo County Transportation Authority. “It is thanks to the voters of San Mateo County who had the wisdom to approve Measure A and provide the tax dollars that make this effort possible, that we are finally moving forward with this much anticipated, long-awaited project.” 

As the primary access to and from US 101 at Burlingame and the only connection to hotels and businesses along the Bayfront, the reconstruction project was listed in Measure A, a half-cent county sales tax approved by voters in 1988. In 2004, more than 75 percent of San Mateo County residents voted to reauthorize the measure for an additional 25 years.

“The existing Broadway interchange is one of the oldest freeway interchanges in the Bay Area,” Caltrans District 4 Director Bijan Sartipi said. “This project will transform it into a 21st century facility, and will provide residents and visitors with a gateway to Burlingame that efficiently moves traffic and is aesthetically pleasing.”

The project will remove the existing four-lane overcrossing and construct a new seven-lane structure approximately 170 feet north of the existing overpass. Broadway will be realigned to extend straight across the freeway from the Broadway and Rollins Road intersection on the west to the Old Bayshore Highway and Airport Boulevard intersection on the east.  The new Interchange will provide added capacity to address traffic demand and improve traffic safety and circulation through the area for motorists, bicyclists and pedestrians.

"We are simply delighted this project is finally moving forward. It will be a great benefit to our families going over to the bayside for baseball and soccer, for Bay Area guests looking for their hotels, and for visitors coming to our shops, restaurants and Auto Row,” Michael Brownrigg, Burlingame mayor.

The on- and off-ramps will be replaced and ramp metering lights will be installed. The pedestrian crossing south of Broadway will remain and there will be additional pedestrian and bicycle improvements at the new interchange.  In addition, the interchange will have enhanced aesthetic and landscaping elements including energy efficient LED lights over the bridge and gateway entry features.

Construction, which is funded by a combination of funds from Measure A, state funds administered by the City/County Association of Governments, the City of Burlingame and the federal government, is expected to be completed in fall 2017.  The project will cost $83 million to complete.
