Document Description
The City of Galt, in conjunction with Caltrans, proposes to modify the Twin Cities Interchange on SR-99 before the year 2013 in order to provide sufficient capacity to accommodate projected increases in regional and local traffic during the next 10 years and provide safe and effective pedestrian and bicycle circulation between East and West Stockton Boulevards. The project would improve traffic congestion at the interchange, provide modern roundabouts at each of the frontage road intersections, provide a new freeway onramp in the southbound direction onto SR-99, provide pedestrian access at the two intersections and a sidewalk on the north side of Twin Cities Road connecting the intersections, and includes ADA upgrades.
