I-95 Express Lanes Virginia Virginia project transforms one of the country’s most-congested highways to an efficient managed lanes system ? LiDAR creates detailed 3-D model ? Design is 99-percent complete in 12 months ? Daily commuters save 10 to 20 minutes HNTB provided design services for the public-private partnership, design-build project that expanded northern Virginia’s I-95 high-occupancy vehicle lanes by 29 miles. The existing, fully reversible two-lane HOV system was retrofitted with a third lane and high-occupancy tolling technology throughout. Because lanes remained open during construction, traditional on-site surveys were not an option. Instead, HNTB used LiDAR to create a highly accurate, highly detailed 3-D model of the facility. Design, which included geometric
