Transit U Improvement Project

Project Introduction

The Transit U encompasses the blocks of 1st and Fremont streets between Mission and Market streets and the intersecting block of Mission Street, which together form a "U" shape that connects Market Street to the Salesforce Transit Center. This project will enhance the streetscape to support high pedestrian and transit volumes in one of the densest parts of San Francisco.

The project proposes:

  • Wider sidewalks along 1st and Fremont streets between Market and Mission streets and the north side of Mission Street between 1st and Fremont streets
  • Corner bulbouts at the intersections of 1st/Market, 1st/Mission, Fremont/Market and Fremont/Mission streets.
  • An enlarged transit boarding island on Fremont Street approaching Market Street
  • Reconfigured travel lanes, commercial and passenger loading zones along 1st and Fremont streets between Market and Mission streets
