The San Gabriel Valley's Temple City opened its excellent new Rosemead Boulevard Project on May 10, 2014. I didn't make it out to the grand opening festivities, but I recently got a chance to bicycle there and experience the new Rosemead Blvd first hand. It's great. All Southern California cyclists should make pilgrimages -- and spend money while you're there.
The project, shown in green on the above map, is on both sides of Rosemead Boulevard for its entire length through Temple City. It extends two miles from Calita Street to the railroad undercrossing near Lower Azusa Road. The area is mostly commercial strips, with some housing, apartments, and single family homes interspersed. Overall, it's suburban, though somewhat older suburban. Most of the commercial buildings are set back far from the street; there are plenty of surface parking lots.
Rosemead Boulevard's protected bike lanes are quite different than L.A. County's first protected bike lanes on Third and Broadway in Downtown Long Beach; both are first class facilities, though. The Long Beach project includes bike signalization at nearly all signalized intersections; as far as I could tell, Temple City didn't make any changes to traffic signals. Traffic signals can markedly increase costs for protected bikeways. Temple City doesn't appear to have skimped on costs, though. The project includes extensive landscaping, and lots of curb-work, including landscaped center-median islands.
Temple City's treatments vary a great deal. Section treatments--see images below--ranged from landscaped-island-protected bikeway to parking-protected bikeway to buffered bike lane to basic bike lane (with and without parking) to short stretches of sharrows.
Below is a pair of images that show a stark contrast between Temple City and its southern neighbor, the city of Rosemead.
