Document Description
This project proposes to construct auxiliary lanes on southbound State Route 99 (SR-99) in Elk Grove, Sacramento County, California between PM 12.7 to 16.0 to improve weaving and merging operations. The proposed auxiliary lanes will reduce traffic congestion by reducing weaving of traffic and will enhance traffic flow through this corridor. Caltrans traffic operations has identified the need for auxiliary lanes at the following locations: SR-99 southbound from Calvine Road/Cosumnes River Boulevard to Sheldon Road and SR-99 southbound from Laguna Boulevard/Bond Road to Elk Grove Boulevard. Project activities would include the construction of auxiliary lanes less than one-mile, installation of ramp meters, replacement of median barriers, ramp widening, and culvert augmentations. The removal of existing chain link fencing, construction of a concrete barrier, and the repositioning of overhead signs are anticipated between the southbound SR-99 lanes and West Stockton Boulevard. Five on-ramp meters will be upgraded on northbound SR-99 at various locations within the existing ramp areas. The project also proposes to widen the southbound off-ramp at Elk Grove Boulevard approximately 300 linear feet south of the gore area. Culverts at various locations within the project area would be installed to accommodate the road widening and new storm drain inlets would be installed at the toe of wall barriers in the shoulder area of the new auxiliary lane. The existing concrete median barrier from 50 feet north of the Elk Grove Boulevard Overcrossing to 50 feet north of the Calvine Road Overcrossing would be removed and replaced with a new median barrier.
