Crews will work nonstop for 72 hours the next two weekends to improve safety and smooth roads around the San Bruno Caltrain station.
Train service will not be interrupted while maintenance work is performed on the grade crossings on Angus Avenue just north of the station, Caltrain spokesman Jonah Weinberg said. Cars will be detoured around the crossing two blocks north to San Bruno Avenue, he said.
Crews will replace the asphalt with new concrete panels; remove worn out ties, rails and ballast for new ones; and perform other work to fix wear and tear. Crews will also improve drainage in the area to prevent flooding, he said.
The biggest difference people will notice are repaved roads that will make driving on the crossings easier, Weinberg said. Passengers going in each direction will board from the same platform during the project.
The work will be done on the southbound side this weekend and on the northbound side next weekend. That process will allow trains in both directions to operate on the same track each weekend.The project should produce some noise, Weinberg said.
The construction will start Friday at 8 a.m. and end Monday at 8 a.m. The same schedule and road closures will be in effect next weekend.
