Revised on 5/12/16

The Truckee River Bridge project is located along Lake Tahoe's west shore near the SR 89 and SR 28 intersection area in Tahoe City, California. The work includes realigning State Route 89 between Granlibakken Road and the junction of State Route 89/State Route 28 (SR 89/SR 28) to replace the structurally deficient Fanny Bridge, and to accommodate traffic demands at the SR 89/SR 28 junction in Tahoe City. The purpose of the project is to reduce traffic congestion and improve the safety and operations of SR 89/SR 28 junction in Tahoe City by addressing: present and future automobile travel demand, pedestrian and bicycle mobility, public transit needs, the structural integrity of the Truckee River Bridge (Fanny Bridge), and emergency access to the West Shore within the Fanny Bridge Influence area. Three roundabouts, a new bridge, a bridge replacement, and realigned shared use paths are proposed with the improvements.

The Dollar Creek Trail project proposes to construct 2.2 miles of new shared-use trail along the north shore of Lake Tahoe near State Route (SR) 28 between Dollar Hill and Tahoe Vista.  The project will include a shared-use trail, a bridge over Dollar Creek, a marked pedestrian crossing at SR 28 and Dollar Drive, and a neighborhood connector at County Club Drive.  The Dollar Creek Shared-Use Trail runs from the Dollar Hill area northeast to Fulton Crescent Drive.
