San Francisco (BCN) — Several San Francisco streets and portions of Interstate 280 will be closed Friday as firefighters from around the state converge on San Francisco

on Friday to attend the funeral service for two firemen who died after

fighting a blaze in the city’s Diamond Heights neighborhood last week.

Southbound I-280 will be closed to traffic from southbound Highway 101 in San Francisco to the Serramonte Blvd. exit in Daly City, Caltrans reports. All transition roads and on-ramps in these locations will be closed. Motorists are advised to expect major delays and to take alternate routes to avoid these areas during these closures.

Fire department spokeswoman Mindy Talmadge said today that at

least 6,000 people are expected to attend the services for Lt. Vincent Perez,

48, and firefighter-paramedic Anthony Valerio, 53.

The pair died of injuries they suffered while battling a fire at a

home at 133 Berkeley Way on June 2. Perez died later that day and Valerio

succumbed to his injuries on Saturday morning.

A vigil will be held for the two men at 7 p.m. Thursday at St. Mary’s

Cathedral at 1111 Gough St., and a joint funeral is planned for 12:30 p.m.

Friday, also at St. Mary’s.

After the funeral, the men will be buried at the Holy Cross

Cemetery in Colma.

The Police Department today released details about street closures

planned from about 9 a.m. to 5:30 p.m. on Friday to make way for the funeral

and procession to the cemetery.

Westbound Geary Boulevard will be closed from Gough Street to

Webster Street, and eastbound lanes will be shut down from Divisadero Street

to Gough Street.

Northbound Webster Street will be blocked from Geary Boulevard to

Ellis Street, and there will be partial lane closures on Gough Street between

Geary Boulevard and Ellis Street.

After the funeral, a procession more than 200 fire trucks will

travel south on Gough Street, then head west on Market Street, south on

Valencia Street, west on 15th Street, south on Dolores Street and merge onto

San Jose Avenue, police said.

From San Jose Avenue, the procession will enter southbound

I-280 and exit at Serramonte Boulevard, then turn onto

Collins Road, then head onto El Camino Real where it will end at the

cemetery.
