RS&H is currently providing inspection services to the Central Texas Regional Mobility Authority for the US 183 South Bergstrom Expressway project. The $743 million project is approximately 50 percent complete.
Set to open in phases starting in 2019, the expressway is expected to be fully open to traffic by mid-2020. The project broke ground in April 2016 and, at the time of the award, was the largest inspection contract for RS&H’s Transportation-Construction Management Practice.
Serving as one of Austin’s most important arterials, the US 183 corridor is a primary route for commuters to and from Austin-Bergstrom International Airport, as well as local destinations east and west of the corridor. With the increase in surrounding population, traffic volumes and vehicle crashes, expansions to the four-lane divided highway were necessary to improve the quality of life in the area.
The RS&H team is providing inspections for the entire project, which includes inspecting reconstruction of existing overpasses, new bridges over the Colorado River, and roadway inspection for retaining walls and concrete paving.
“We have a team of about 24 inspectors, including our sub-consultants,” said RS&H South Texas CEI Leader Cris Peña, PE. “We’re conducting full construction inspection of essentially anything that is attributed to the project.”
Peña serves as RS&H’s Project Manager for the US 183 South project. The updates will provide Central Texas drivers with a signal-free route to decrease delays in their daily commutes.
“This project will improve mobility and add capacity to the corridor,” Peña said. “Prior to construction, the corridor primarily consisted of two lanes in each direction, so expanding to a 12-lane divided freeway section will be a big improvement to previous traffic conditions.”
When the project is complete, US 183 will be a tolled expressway, carrying both tolled and non-tolled travelers. The reconstruction includes up to three general purpose, non-tolled lanes in each direction and three tolled expressway lanes in each direction. The project will also bring multimodal connections to the community that includes a 10-mile continuous shared use path, 16-miles of bike lanes along the northbound and southbound general purpose lanes, and new pedestrian bridges that cross over US 183, along with visual enhancements and landscaping.
