Reduced congestion, better traffic flow and improved safety for road users are the aims of a new project for Orange County in the 972 US State of California. The 3300 Orange County Transportation Authority (OCTA) has selected Stantec to carry out two long-term projects that affect traffic density on sections of the 91 Freeway and Interstate 405 (I-405). Stantec's Irvine office will lead the work, which is expected to begin in July 2011 and continue into 2012.

On I-405, Stantec will carry out a plan by the OCTA vision to design a continuous access system, which will allow commuters to enter or exit at will from the existing HOV lane between the 73 toll road and Interstate 5 interchanges. Work on this project will include the preparation of plans, specifications and estimates; a project study report; and environmental documentation; among other elements. On the 91 freeway, Stantec will carry out a comprehensive study on the stretch lying between the 55 and 57 freeways. This will investigate the feasibility of adding additional road capacity, including an additional, mainline lane and will include preliminary design and operational characteristics.

This study will also look at improvements for the 55 and 91 freeway interchange complex as well as the evaluation of overall road capacity needs between the two major interchanges.
