Better Roads August 2014 13 T he California Department of Transportation (Caltrans) is investing $3.2 billion to im- prove I-5 in Los Angeles County from Burbank to the Kern County line and from the Los Angeles/Orange County line to I-605. There are about 17 proj- ects to complete these improvements: The Santa Ana Freeway (I-5) South Corridor Improvement Project extends nearly seven miles from the Los An- geles County/Orange County line to I-605 to widen the freeway, bridges and overcrossings adding one High Occupancy Vehicle (HOV) lane and one general-purpose lane. In addition to the HOV connectors, there will also be new/realigned on- and off- ramps; new/realigned bridges; lanes specifically for trucks; additional gen- eral purpose lanes; upgraded frontage roads; new pavement; reconfigured interchanges; and grade separations. The entire project is slated for com- pletion for the end of 2015. A $1.6 billion package of six proj- ects in the overall project will add nearly 14 miles of carpool lanes on I 5 from the Los Angeles County/ Orange County line to the San Gabriel River Freeway (Interstate 605). When completed, motorists will be able to travel seamlessly in a carpool lane from Downey to San Juan Capistrano, a distance of 44 miles. This project requires extensive pre- planning with a heavy emphasis on logistics. The temporary lane closures on the I-5 south corridor, the closures and detours of main freeway exits, the route the trucks hauling the gird- ers must take along with CHP escorts, along with arriving on-site at the des- ignated times for crane activities and completion of the activities within the allowable freeway closure times is also highly notable. The project consists of multiple bridges. The San Antonio bridge is being constructed in three stages. Once the first stage is completed, all traffic will need to be converted over to the new bridge section. The second stage is comprised of demol- ishing a mid-section of the existing bridge then adding new girders and tying it back into the first stage. Then A $1.6 billion package of the overall $3.2 billion invested for the freeway and multiple bridges will add nearly 14 miles of carpool lanes to make travel seamless for motorists.
