The City of Elk Grove, in cooperation with the County of Sacramento Department of Transportation, the City of Sacramento, Caltrans, and FHWA, reconstructed the Sheldon Road/State Route 99 (SR 99) interchange, the associated frontage road alignments, and access ramps. The original 1950’s structure was vastly undersized to accommodate the increasing number of residents within the City of Elk Grove who relied on the interchange to access the highway.
The project replaced the two-lane overcrossing with a nine-lane facility with three through lanes and two left-turn lanes in the westbound direction and three through lanes and one right turn lane in the eastbound direction. Sheldon Road was widened from Lewis Stein Road to Power Inn Road to provide for three through lanes in each direction.
In addition, the reconfigured interchange provided:
- Two lane southbound loop off-ramp in the SW quadrant
- A 400 meter auxiliary lane in advance of the southbound loop off-ramp
- Diagonal southbound on-ramp in the SW quadrant
- Two lane northbound loop on-ramp in the southeast quadrant with one mixed flow lane and one HOV bypass lane
- Diagonal northbound off-ramp in the NE quadrant with two mixed flow lanes and one HOV bypass lane
In the north west quandrant of the project, the West Stockton Boulevard intersection with Sheldon Road was aligned with the southbound ramp intersection. East Stockton Blvd was relocated approximately 280 meters to the east of its original location.
BRI provided ROW planning services, ROW cost estimation, and acquired rights of entry for the environmental studies as a subconsultant to the engineering design firm. Special considerations had to be made to the design to incorporate a historic cemetary within the project footprint.
In order to construct the project, BRI was selected to provide the appraisal, acquisition and relocation services. The project required appraisals and acquisition services for 46 properties resulting in 9 full property acquisitions, 37 partial acquisitions, 7 business relocations and 11 residential relocations.
