ⓘ Junipero Serra Boulevard

Junipero Serra Boulevard is a major boulevard in and south of San Francisco named after Franciscan friar Junipero Serra. Within the city, it forms part of the route of State Route 1, the shortest connection between Interstate 280 and the Golden Gate Bridge. The remainder, in San Mateo County, was bypassed or replaced by I-280, the Junipero Serra Freeway. The boulevard was one of several new roads built along the San Francisco Peninsula before the age of freeways, and became a state highway known as Route 237 in 1956, receiving the State Route 117 designation in the 1964 renumbering, only to be deleted from the state highway system the next year. Two other regional highways - Bayshore Highway and Skyline Boulevard - were also upgraded into or bypassed by freeways.


1. Route description

Junipero Serra Boulevard begins at exit 44 Avalon Drive of I-280, and travels north along the east side of I-280 as a four-lane divided highway with minimal intersections, just east of the ridge line of the San Francisco Peninsula that Skyline Boulevard SR 35 travels along. The median ends when it crosses Hickey Boulevard; the portion of Hickey Boulevard east from Junipero Serra Boulevard to El Camino Real SR 82 was built as part of that portion of Junipero Serra Boulevard to the north. The boulevard continues northwards with occasional intersections, some with access to I-280, before crossing to the west side of I-280 just north of Washington Street in Daly City and back to the east side north of School Street. At John Daly Boulevard, Junipero Serra Boulevard crosses I-280 for the final time and becomes part of SR 1; the northbound lanes simply cross over I-280, merging with the ramp that carries SR 1 from I-280 onto the boulevard, but southbound traffic must pass under Daly Boulevard, exit and loop over the bridge it just passed under, and then turn right onto Junipero Serra Boulevard.

Just beyond Daly Boulevard, Junipero Serra Boulevard enters San Francisco as a six-lane highway, expanding to eight lanes after the interchanges with Alemany Boulevard and Brotherhood Way. SR 1 soon turns off to the northwest onto 19th Avenue, with three lanes making the turn in each direction and six three in each direction remaining on the boulevard. The final section of Junipero Serra Boulevard has frontage roads for local access, and is planted with trees between the main and frontage roadways. At Ocean Avenue, the K Ingleside line of the San Francisco Municipal Railway enters the median, remaining there until the boulevard ends several blocks later at St. Francis Circle. At this five-way intersection, Sloat Boulevard heads west, St. Francis Boulevard east, Portola Drive northeast, and West Portal Avenue north-northeast, taking the rail line to the Twin Peaks Tunnel.


2. History

Between 1899 and 1915, the city of San Francisco built an "automobile boulevard" from the end of the existing Corbett Avenue now Portola Drive at Ocean Avenue south past the Ingleside Race Track to the county line, where it continued to School Street in Daly City then part of Colma. At the north end, it connected with Parkside Boulevard now Sloat Boulevard and Dewey Boulevard. The city Board of Supervisors named the new boulevard after Junipero Serra in 1908.

San Francisco and San Mateo County formed Joint Highway District No. 10 on September 4, 1928 to fund and construct an extension of the boulevard south to Burlingame. An improvement of the existing road north of School Street was completed in 1930; an extension continued the roadway to Edgemar Road now Eastmoor Avenue in the early 1930s, and in 1933 it reached El Camino Real US 101, now SR 82 in South San Francisco. To the south, Santa Clara County opened a section of the planned road past Stanford University on July 11, 1932. This was never connected to the remainder, though a route that would incorporate Alameda de las Pulgas was proposed. Construction continued at the San Mateo County end into San Bruno, opening to Sneath Lane in 1940 and Crystal Springs Road in the early 1950s; a planned continuation to Millbrae Avenue was never built. Three grade separations were built along the road: two built ca. 1950 and still present at Brotherhood Way and Alemany Boulevard in San Francisco and a third built by 1947 at Washington Street in Daly City. The total cost of the road between the city line and Crystal Springs Road was over $3 million, with over half the money normally coming from San Francisco.

A 1956 law transferred the extension, from the south junction with Alemany Boulevard now John Daly Boulevard south to Crystal Springs Road, to the state as State Highway Route 237, and dissolved the joint highway district) The stub connection to El Camino Real was turned over to the city of South San Francisco to maintain as Hickey Boulevard.

By 1955, a Junipero Serra Freeway was planned, beginning at the Park Presidio Freeway near the south end of 7th Avenue, tunneling under Golden Gate Heights, and heading south into San Mateo County via Junipero Serra Boulevard. This was also included in the preliminary Interstate Highway System plans as part of a loop around the San Francisco Bay, and was added to the state highway system as Route 239 in 1957 for this reason. The eventual path of this freeway which was never built in San Francisco, part of I-280, generally paralleled Junipero Serra Boulevard to Crystal Springs Road, and in fact replaced the boulevard south of Avalon Drive. However, south of Crystal Springs Road, a more westerly route along Skyline Boulevard SR 35 was chosen. The state highway along Junipero Serra Boulevard, which had become Route 117 in the 1964 renumbering, was turned back to San Mateo County in 1965. The state constructed the replacement freeway I-280 in the mid-to-late 1960s and early 1970s, and generally preserved the old boulevard as a frontage road north of Avalon Drive, though the grade separation at Washington Street was destroyed. A short stub near Crystal Springs Road is now ramps connecting I-280 with Cunningham Way.
