Document Description
The California Department of Transportation (Caltrans) proposes the Alta Capital Maintenance Project on Interstate 80 between Post Miles 33.00 and 44.90 in Placer County. The purpose of the project is to preserve and extend the service life of the pavement by improving existing fair and poor condition pavement to good condition with Capital Preventative Maintenance (CAPM) strategies. The project proposes to restore the functionality and extend the service life of drainage systems/culverts in either fair and/or poor condition. The project proposes to extend the eastbound lane separation taper at the State Route 174/Interstate 80 Separation (Bridge No.19-0086) off-ramp and the truck climbing lane on the eastbound side of the Long Ravine Bridge (Bridge No. 19-0089).
