The Orange County Transportation Authority (OCTA) and the California Department of Transportation (Caltrans) District 12 are currently implementing the 91 Freeway Improvement Program, a series of projects intended to increase capacity, improve operations and/or relieve congestion on State Route 91 in Orange County. In general, the 91 Freeway Improvement Program will add new general-purpose lanes, improve operations, reconstruct and/or realign on and off-ramps, widen bridges, construct retaining and/or sound walls as necessary, as well as make various other operational improvements along this commuter and commercial transportation corridor.
What project will next be constructed on the 91 Freeway in Orange County?
Caltrans District 12 and OCTA are expected to begin construction on the 91 Westbound Auxiliary Lane Project in late 2013/early 2014. This will be the fourth in a series of improvement projects on the 91 Freeway in Orange County. Since December 2010, OCTA and Caltrans have added 18-lane miles to the 91 Freeway between Interstate 5 and State Route 241. (Currently, Caltrans and OCTA are building the 91 Westbound Lane Widening Project between State Route 57 and Interstate 5. This project, which broke ground in May 2013, will add a new 4-mile westbound lane to this key stretch between the cities of Anaheim and Fullerton. For more information on this project, click here.)
What operational benefit will the 91 Westbound Auxiliary Lane Project provide?
The project will improve the 91 Freeway in the northeastern part of the City of Anaheim by extending a westbound lane from the northbound (NB) State Route 55/WB SR-91 connector through the Tustin Avenue interchange. In addition, a WB auxiliary lane from east of the NB SR-55/WB SR-91 connector to the Tustin Avenue off-ramp will be reconstructed. Together, these reconfiguration improvements are expected to relieve existing and future operational problems between the connector and the Tustin Avenue off-ramp. When completed, motorists heading westbound on the 91 past the Tustin Avenue interchange from the NB SR-55/WB SR-91 will have the option to do so on a general-purpose lane, while motorists exiting at Tustin Avenue will be able to do so on an exit-only lane, thereby reducing merging and weaving and improving traffic flow in this area.
What are the project limits?
The project area will span from approximately Lakeview Avenue on the east, to just past Tustin Avenue on west. The project is about 2-miles in length. Along this stretch, construction crews will undertake roadway work largely behind k-rail. Crews will also be working at the Riverdale Avenue overpass, the Santa Ana River bridge as well as the Tustin Avenue interchange.
What kind of closures can commuters expect as part of this project?
The majority of work on this project will occur behind k-rail safety barriers. Non-peak/overnight closures of lanes and ramps will be necessary for such work activities as, but not limited to, restriping, installation of k-rails, erection and removal of falsework and restoration of the freeway to its final condition. A Traffic Management Plan will be implemented and will include safe and direct detours for commuters traveling the project area when temporary lane reductions and/or ramp closures are necessary to perform the aforementioned work. Caltrans will provide closure information. Additionally, a temporary impact of up to four months is expected at the Santa Ana River Channel bicycle path. A temporary detour for cyclists will be implemented and available.
