Driving home from Berkeley early this morning around 1:30 AM...saw Caltrans crews working on the signage for the I-80 westbound ramp at 5th Street in SF (the ramp that used to carry US 40 and 50 to surface streets prior to the 1950s).
Essentially they were adding the external left exit tab (which had been missing for a couple of weeks) to this sign. The previous sign had an internal exit tab dating from about 2009 or so.
Interesting to contrast that with another 2022-era sign install set, the stretch of US 101/Bayshore Freeway between the Central Freeway and Alemany Maze, where all the new signs have internal exit tabs (particularly at Silver Avenue and at the ramps to I-280)! The signs along this segment replace retroreflective, no-exit-number installations from around 2000-2003.
