As part of a joint venture, Security Paving constructed a 2-lane elevated HOV connector within the median of I-5 and SR 14 to join the southbound and northbound HOV lanes on I-5 and SR 14, and constructed sound walls at the I-5/SR 14 interchange. The HOV connector is 15 stories tall, nine football fields long, and arcs gracefully, belying the tons of concrete and steel composition.
Construction helped to provide a seamless transportation system and allowed carpoolers a freeway-to-freeway transfer without leaving the carpool lane. The project also added 1.8 miles of 24/7 HOV lanes (for two-person-plus carpools) to the interchange area; constructed major retaining walls; and widened the West Sylmar overhead bridge, the Sierra Highway undercrossing, the southbound I-5 truck route undercrossing, and the mixed-flow connectors between I-5 and SR 14. When completed, it provided continuous HOV lanes from Antelope Valley to major metropolitan regions in Los Angeles County.
