Thanks to David Gwynn for sending me this Arrow Map, created by the RL Polk Company.
Comments: This is one of the VERY FEW maps to show both signed routes as well as the LRNs (used until 1964). For those not in the know, here is a guide to which routes corresponded to which LRNs:
LRN 2 - US 101 (entire state), this was originally created in 1909 for the
El Camino Real. (Notice that Mission Street has never been US 101 in San
Francisco itself, but 101 has always taken a roundabout routing around the
Mission District.) This is now CA 82 and I-280 south of the Bayshore.
LRN 55 - CA 5 (now CA 35), or Skyline Boulevard. This MAY have been
the LRN for the Great Highway freeway, which only shows up on very early
(1947) planning maps.
LRN 56 - CA 1 (which at the time used Skyline and Alemany (now John Daly)
Blvds in Daly City; the portion of CA 1 west of CA 35 to Pacifica had been
demolished in an earthquake in 1957). Includes the planned I-280 freeway
routing on Park Presidio and Junipero Serra. This was (1998) being
planned in its entirety, albeit as a private toll road.
LRN 68 - Bypass US 101 (now US 101); the Bayshore Freeway, and US 40/50 (now
I-80), the San Francisco Skyway.
LRN 223 - I-80 Western Freeway, never built, but on a much different alignment
from the Fell Street corridor. (The Fell Street corridor may have its
own tunnel, but only on partial sections of the route.)
LRN 224 - I-480, the Embarcadero Freeway, including the unbuilt Lombard Street
portion (which would run right through Telegraph Hill AND the Crookedest
Street in the World). Part of it was reconsidered for construction
in 1998 as tunnel.
LRN 225 - Alemany Boulevard between CA 1 (Junipero Serra Freeway) and then-US
101 (now I-280); this is now the approximate corridor for I-280. The
sender of this map, who maintains an interesting supermarket history site
at http://www.groceteria.net, used
to frequent a Lucky market at this area; it is being rebuilt as an
Albertson's.
LRN 237 - Junipero Serra Boulevard/Freeway south of John Daly (then Alemany)
Boulevard; now I-280.
LRN 253 - A. Southern Freeway east of US 101, this was CA 87 and CA 82 but
is now I-280.
B. East Bypass
through Candlestick Point and Hunters Point, which is now planned CA 230,
but mostly was proposed CA 87.
LRN 289 - CA 87 between the current ending at US 101 in San Jose to the East
Bypass, no longer proposed.
Interestingly, there is no LRN for US 40/50 (now I-80), the Bay Bridge and San Francisco Skyway.
