New Lanes on the SR-91
Caltrans and OCTA opened up a new six-mile lane in each direction of the 91 Freeway between SR-55 and SR-241 on February 21, 2013. Thanks to the support of local cities and Orange County taxpayers, Caltrans and OCTA are increasing capacity, improving driving operations and helping relieve congestion for the nearly 300,000 commuter and commercial motorists who drive this key stretch of the 91 every day.
In addition to the newly opened general-purpose lanes, the Lakeview Avenue, Imperial Highway and Yorba Linda Boulevard/Weir Canyon Road bridges have been widened, and 15 on- and off-ramps have been reconstructed and realigned to make for safer and more efficient transitions for motorists entering and exiting the freeway.
Project Benefits – Creating Capacity, Improving Operations
Beyond the new lanes, the $74.3 million project delivers several capital and operational benefits, including:
- Standardized 12-foot lanes and 10-foot shoulders
- Widened bridges at Lakeview Avenue, Imperial Highway and Yorba Linda Boulevard/Weir Canyon Road
- New striping, signage, lighting and safety barriers throughout the project limits
- A new 1 ½ mile soundwall on the eastbound side of the freeway beginning east of Imperial Highway
- A bioswale drainage facility
Also, motorists exiting eastbound at Lakeview Avenue, Imperial Highway and Yorba Linda Boulevard/Weir Canyon Road now benefit from a new, second exit lane, making getting off the freeway smoother and getting home easier.
Major operations on the 91 Westbound and Eastbound Lane Addition Project have been completed. Construction crews are currently wrapping up “punch list” items and a landscaping plan will be implemented in mid to late 2013.
In addition to being part of Orange County’s Measure M Program, the project was funded by the State Transportation Improvement Program (STIP) and the Corridor Mobility Improvement Account (CMIA). The project’s total estimated cost is $74.3 million. Of this, nearly $62 million covered construction costs.
