SAN FRANCISCO — The main approach to the Golden Gate Bridge from San Francisco is set to come down, as crews replace it with a new $1.1 billion parkway.

Officials announced on Monday that construction workers will demolish Doyle Drive at the end of the month. The roadway will be closed from 8 p.m. on Friday, April 27 to 5 a.m. on Monday, April 30 as dozens of hydraulic hammers bring the structure down and a temporary bypass is set up.

Residents are being warned of noise and traffic jams throughout the weekend. Traffic to the Golden Gate Bridge from San Francisco will be redirected to Highway 1.

Doyle Drive has been deemed seismically unsafe.

It is being replaced with the 1.6-mile Presidio Parkway. The project will include two tunnels when it is completed.
