NDOT Opens New I-11 Segment to U.S. 95 Interchange on May 23 in Boulder City

Post Date:05/17/2018 1:42 PM

BOULDER CITY, NEV. – The Nevada Department of Transportation (NDOT) will open a 2.5-mile-long section of the new Interstate 11 between Foothill Drive in Henderson and U.S. Highway 95 in Boulder City at 7 a.m., Wednesday, May 23. Fisher Sand & Gravel Co. is the general contractor. Pieces of the new interstate opened in phases starting last year. (The Regional Transportation Commission is still working on the remaining 12.5-mile second segment of new interstate that should open later this summer).

The $83 million Interstate 11 Phase One project, which broke ground in late 2015, consists of building a full diamond interchange at Railroad Pass with a loop ramp, plus a 600-foot-long two-lane cast-in-place flyover bridge from southbound I-11 to eastbound U.S. Highway 93 toward Boulder City. Other project components include a new 1.5-mile-long asphalt frontage road linking Henderson with the Railroad Pass interchange, plus replanting 20,000 cacti, placing decorative rock, and installing 5 miles of tortoise fencing.

The stretch of highway currently sees 34,000 vehicles daily with heavy truck traffic. It’s identified in both the North American Free Trade Agreement (NAFTA) and CANAMEX Corridor. Department officials consequently opted to use concrete pavement due to its longevity, which, federally funded studies show, costs up to 28 percent less in the long run than asphalt. It also reduces rutting and potholes, thereby cutting maintenance expenses by up to 75 percent.

The project’s visual centerpiece is a 1,200-foot-long, 28-foot-tall cast-in-place concrete retaining wall with multi-colored graphics and extruded Cor-Ten steel figures and objects that illustrate scenes from the construction of Hoover Dam. It reflects the region’s social, cultural, and economic history, acting as an iconic graphic gateway to Boulder City. The textured retaining wall is coated with a special anti-graffiti film that serves as a deterrent for taggers. Phase one also reconnects the railroad tracks previously severed by U.S. Highway 93 with a new 364-foot-long, 23-foot-wide concrete bridge that allows the mainline freeway to pass underneath. Meanwhile, a steel prefabricated pedestrian bridge connects the River Mountains Loop and Henderson trail systems.

Interstate 11 marks the first new infrastructure to the Interstate Highway System since it was deemed complete on October 14, 1992 with the opening of I-70 through Glenwood Canyon, Colorado.
