I posted an update last week on the transit projects funded by Measure R. Some of the major road projects get their turn today.

The following list just looks at some of the major road projects that are benefiting from Measure R dollars. Many other smaller projects around Los Angeles County ranging from median improvements to repaving have been completed or are underway.

And that doesn’t count the dozens of smaller road projects that will be paid for by the 15 percent of Measure R revenues returned to local cities for use on transportation-related projects and expenses.

I-5 HOV: The project to construct one carpool/HOV lane in both directions between the 134 and 170 freeways is under construction.

I-5/SR-14 HOV Direct Connector: The project is under construction and is building ramps that will allow carpoolers to travel between the 5 and 14 freeways without leaving the HOV lane.

I-5 Carmenita Road Interchange Project: The widening of the 5 freeway on either side of the Carmenita Road overpass is under construction.

I-5 North County Capacity Enhancements: Truck lanes between the 14 freeway and Pico Canyon are under construction. Other improvements, including more truck lanes and freeway improvements, are in the study and planning phases.

South Bay Operational Improvements: The project will help fund a number of on- and off-ramp improvements (such as widenings, auxiliary lanes and metering) primarily in Carson, Hawthorne, Inglewood, Lawndale, Redondo Beach and Torrance, as well as parts of the city and county of Los Angeles. Some improvements are under construction; many others will be built between 2013 and 2015.

I-5 Widening I-605 to Orange County Line: The project will add one general and one HOV lane in both directions for 6.4 miles. The project is in its final design phase and will be built in six segments. The Alondra segment is under construction and construction contracts were just awarded for segments three and four.

Arroyo Verdugo Operational Improvements: The project a help fund various projects within the subregion, including two that will have groundbreaking this month: road crossing improvements for Grandview Avenue and Sonora across the  Metrolink tracks in Glendale. Other projects involve upgrades to various intersection and traffic signals in Glendale, Burbank and La Canada-Flintridge.

Las Virgenes Malibu Operational Improvements: The project will help fund various traffic improvements in the far western part of Los Angeles County. One prominent one is under construction i the 101 and Lindero Road interchange improvement.

Countywide Soundwall Construction: Four different projects are scheduled to be completed in the next two years, including I-405 Devonshire to San Fernando Mission Blvd; I-405 San Gabriel River to Atherton; SR-134 Cahuenga Boulevard to Riverside Drive, and; I-605 Slauson Avenue to Route 10. Soundwalls on the I-210 between California Avenue and Santa Anita Avenue were completed this summer.

SR-138 Capacity Improvements: The project will be constructed in six segments and widen the 138 between Avenue T in Palmdale and Highway 18 in Llano, a distance of 54 miles. This part of the project is in its preliminary engineering and final design phase. In addition, widening for the 18 will be environmentally cleared between I-5 in Gorman and Lancaster as part of the project.

I-605 Corridor Hot Spot Improvements: An alternatives analysis is expected to be completed by the end of year to determine potential projects to improve traffic flows and/or capacity at the 605’s junctions with the 60, 91, 5 and 405 freeways.

I-710 Corridor Project: The project proposes to improve I-710 from Ocean Boulevard in Long Beach to State Route 60 in East Los Angeles, a distance of approximately 18 miles. In addition to widening the existing highway and possibly adding truck-only lanes, the proposed project includes improvements to the 710’s intersections with the I-405, SR-91, and I-5 and local arterial streets throughout the project limits. The project’s draft environmental impact statement/report was released this past summer and the comment period recently concluded. The project team is currently reviewing public comments and working toward recommending a preferred alternative. Project website

SR-710 study: The project is studying transit and/or road improvements in the western San Gabriel Valley to address traffic impacts from the gap in the 710 between Alhambra and Pasadena. The project is currently in its alternatives analysis phase. Project website

High Desert Corridor: The environmental studies — funded by Measure R — are underway for a proposed 63–mile freeway between the 14 and 18 freeways that would link the Antelope Valley and Victor Valleys. Project website
