OVERVIEW

The Riverside County Transportation Commission is building the Route 91 Pachappa Underpass in Riverside. The project will include construction of a retaining wall and removal of part of the overhead railroad bridge. Construction will take place from April 2020 to mid-2021.

Construction contract was approved at the November 13, 2019 commission meeting.  Work begin in early April 2020.

Construction will begin in spring of 2020 with work anticipated to be completed in mid-2021.

This project includes work that was deleted from the Caltrans Route 91 High Occupancy Vehicle (Carpool Lane) Project. In December 2016, the Commission approved the removal of this work from that project and authorized this separate Pachappa Underpass Project. Most of the work consists of removing the Pachappa Underpass temporary bridge and its associated retaining walls and building a new retaining wall to support the final Union Pacific Railroad alignment.
