Document Description
Note: Final IS/EA is available on: http://www.dot.ca.gov/d4/documents-environmental/116-121intersection/sr116-121-is-ea-admin-fed-vol-1-master-04062018-clean.pdf http://www.dot.ca.gov/d4/documents-environmental/116-121intersection/sr116-121-is-ea-admin-fed-vol-2-appendices-master-04032018-clean.pdf The intersection improvement project has two proposed alternatives. The Roundabout Alternative includes construction of a hybrid multilane roundabout with 180 degrees of the circulatory roadway having two lanes, a full right-turn bypass lane in the northbound direction, and a partial right-turn bypass lane in the westbound direction. The Signalized Intersection Alternative proposes to introduce a four-way traffic signal to the project intersection. Both Build Alternatives include construction of pedestrian and bicycle facilities.
