SR 1 Major Investment Study

Study Description
In response to increasing traffic volume and congestion along Highway 1 / Santa Rosa Street between Stenner Creek Road and Walnut Street, the State Department of Transportation (CalTrans) and the San Luis Obispo Council of Governments (SLOCOG) commissioned a study to investigate solutions for improving safety, operations, community enhancement, and access along HWY 1.

What is a Major Investment Study (MIS)?
A Caltrans MIS is a planning document that investigates operational, safety and capacity issues along a corridor that is too complicated to analyze in a project specific planning document. The MIS investigates long-term issues and associated improvements that can be programmed to mitigate future traffic issues that will develop and corridor conditions change. The document can analyze adjacency issues, such as neighborhood cut-through.
