DISCUSSION / BACKGROUND
The Diamond Springs Parkway - Phase 1A - SR-49 Realignment Project (Project) is necessary to construct the realignment and widening of State Route 49 (SR-49) between Pleasant Valley Road and Bradley Road. The Project includes roadway improvements on SR-49, as well as roadway excavation, HMA paving and dike, concrete curb, gutter, and sidewalk, signing and striping, permanent and temporary fence removal and construction, drainage improvements, signal modifications, retaining wall, and underground utility construction. Approximately 23,000 cubic yards of material will need to be excavated in order to lower the profile of Lime Kiln Road approximately 15 feet to conform to the widened section of SR-49. As a result, Lime Kiln Road will be closed for up to ten (10) weeks for reconstruction. The total estimated cost for the Project’s construction phase is $11,657,000.
This Project is a two hundred and fifty (250) working day contract. Lime Kiln Road will be fully closed to traffic for seventy (70) calendar days from Lime Plant Road to SR-49 (approximately 500 linear feet of road closure) in each direction of travel. Access for local residents and visitors, as well as emergency personnel and law enforcement, will be via detour to China Garden Road per the Project Detour Plan.
