SR-91 Improvements PA/ED, RCTC

As a subconsultant to Parsons Brinckerhoff, RMC, Inc. is currently providing preliminary engineering and project management services, during the PA/ED phase of this project.  The alternatives considered will increase freeway capacity along SR-91, potentially by the extension of the 91 Express Lanes to Riverside.  Because of the strict right-of-way constraints, the project team is exploring creative geometric options to mitigate these limitations.  The improvements are being planned in conjunction with several other enhancements along SR-91, requiring close coordination with all involved agencies.  The development of this project follows the recommendations of the planning documents prepared for this corridor, including the SR-91 Implementation Plan and Riverside County-Orange County MIS.

This project represents the ultimate build-out of SR-91 and requires the project team to ensure that the footprint accommodates all stakeholder interests that reach far into the future.  The project team is striving to meet a 42-month schedule by building on the work from the MIS and interfacing with the decision makers and resource agencies. This aggressive schedule will allow the client to meet their planned 2015 delivery date. 

RMC, Inc. is playing a major role in ensuring that consensus is built among all stakeholders on the design concepts from the beginning, as well as providing schedule and budget control for the entire project.  The RMC, Inc. team is responsible for preparing the construction staging, utilities, and drainage concepts for this 10-mile stretch of SR-91.
