East Bypass
East Bypass
Red arrow points to dotted route of CA 230 (East Bypass) in 1963 planning
map. Note that the Southern Freeway is still under construction east
of US 101, which is labeled as BYP 101.
Length: 2.5 miles (San Francisco), 4.5 miles (constructed portion in San
Jose), 45 miles (unconstructed portion between SF County Line and San Jose)
Routing in San Francisco: Candlestick Point, Hunters Point
Construction: Proposed route (rejected in 1970 and 1976, but still proposed
by CalTrans)
Route Numbering: CA 87 (1964-1968,1970), CA 230 (1970-present)
The CA 230/CA 87 east bypass (no official name ever given) was one of the later freeway plans for San Francisco, and may still be in existance as the Southern Crossing continues to be reconsidered for eventual construction.
CA 87 currently runs between CA 85 (the US 101 bypass of San Jose) and US 101 in San Jose. Originally, it was to have extended northward as a likely tunnel between San Jose and Candlestick Park. A definite attempt at a fantasial, "futuristic" highway, the portion between San Francisco and San Jose was canceled around 1970 was probably canceled for the same reason the I-480 tunnel was never built - a supposed "psychological" barrier for potential travelers. However, this does not explain why the Big Dig in Boston is currently being finished, with much the same psychological barriers.
When CA 87 was scaled back to Santa Clara County, CA 230 replaced its routing between Candlestick Point and I-280 near Army Street. However, its main intent was to feed to the Southern Crossing bridge between Alameda and Army Street, which is still currently under on again/off again debate, although CA 230 was essentially considered to be canceled after 1976.
The 3rd Street interchange on US 101 may have been an attempt to start construction on the east bypass, as it is quite massive compared to most street interchanges in the City. Yet this may have been a vestige of Bypass US 101's routing on Bayshore Boulevard.
