Movable barriers were eventually incorporated along a 16 mile section of the I-15 Express Lanes, with three lanes allocated for southbound during the morning hours Monday through Thursdays. The three to four center lanes would be adjusted to accommodate traffic flow with a special truck that can move median barriers. Under this plan, the freeway would be widened for southbound traffic in the morning and for northbound traffic in the evening. Some planners pitched the idea of creating a "zipper" system for Interstate 15. The auxiliary lanes enhanced traffic flow between freeway entrances and exits, while restriping allowed more lanes to fit in a narrow area, such as across the Lake Hodges bridge. In some cases, this included restriping shoulders and narrowing lane widths to accommodate more freeway lanes. Short-term solutions to this problem included adding more "auxiliary" lanes to Interstate 15. The high-tech component included sensors embedded in the concrete to make adjustments to the roadway to facilitate traffic flow. The total project cost was estimated to be around $535 million in May 2001. This initial money funded a study to plan out the managed lanes concept. Governor Gray Davis' traffic relief plan, released May 3, 2001, allocated $5.5 million to a high-tech managed lanes concept along Interstate 15 between California 163 and California 78. The need to improve Interstate 15 through this corridor did not go unnoticed at the state level. Much of this traffic was due to new housing developments and the lack of major surface arterials that carry north-south traffic.

Analyst projections in the early 2000s estimated that I-15 will carry upwards of 330,000 vehicles, a 17% increase.

Counts over the intervening years rose to 281,000 cars per day, with the busiest section located between California 163 and Miramar Way. In 1988, Interstate 15 saw only about 196,000 cars per day. With several hundred additional homes planned in Spring 2001, the Rancho Encantada development further advanced discussion of the impact of new housing against the existing highway infrastructure. One of the tenets of this agreement included Black Mountain Ranch paying for highway improvements, including along I-15 and California 56. These propositions opened parts of the City of San Diego's future urbanizing areas for development. Two local propositions, K and M, were approved by the electorate. Black Mountain Ranch made the news during the Fall 1998 campaign. Explosive development planned in 1998 included 12,800 houses planned in the Interstate 15 corridor, including Black Mountain Ranch (5,400), Torrey Highlands Ranch (2,693), and Pacific Highlands Ranch (4,974). Fast-paced growth and a North San Diego County housing boom fueled traffic count increases along this highway, causing many to reconsider purchasing a home along the Interstate 15 corridor. Interstate 15 has experienced the most traffic growth of any freeway in San Diego County. 66-91 between Exits 181 and 184 via L Street and Main Street the eastern leg extends beyond I-15 to Interstate 40 at Exit 1. 66 between Exits 150 and 153A along Seventh Street and D Street the portion along D Street overlaps with California 18

The 20 mile system is free of charge for carpools, motorcycles, public transit vehicles and permitted clean air vehicles. Tolled Express Lanes accompany Interstate 15 north from the merge with SR 163 by MCAS Miramar to SR 78 at San Marcos and Escondido. 91 remains in eastern Idaho and northern Utah.

With all the greenery, it was hard to believe that this area had burned in the October 2003 Cedar Fire. Interstate 15 approaches the Marine Corps Air Station at Miramar north of California 52 in the springtime.
