Sundt is beginning the final stages of a $68 million project to improve a segment of Loop 375 Transmountain Road near El Paso, Texas. The team is finalizing the grooving of the bridge decks and putting the final finishes on the stamped concrete under the new bridges. Overhead sign structures are in place and landscaping is about 70 percent complete. What’s left before the project is complete in mid-May? Traffic signalization, electrical work below some of the bridges, and asphalt paving.
The heavy civil construction project includes widening the 3.5-mile stretch of roadway from two to four lanes (with frontage roads), building four grade-separated intersections, hiking and biking trails, and exit and entrance ramps. The project also includes direct connectors from Loop 375 west to Interstate 10 east and I-10 west to Loop 375 east.

Sundt created a 3D model of the new sewer line to identify potential conflicts with other utilities.
Don’t like conflict? If it’s utilities you’re talking about, 3D modeling might be the answer. That’s how Sundt identified potential problems – and showed our client how to solve them – on a roadway reconstruction project in El Paso, Texas.
“After evaluating the planned sewer line corridor and comparing it to the existing utilities, we found several potential conflicts,” said Rob Manning, Sundt Project Manager for the $14 million Country Club Road widening project. “We collected data by uncovering the actual utilities through potholing, then took GPS survey shots of each utility and created a 3D model that includes the planned sewer line placement. We presented our findings and suggestions to the city and its engineer, and they used the information to redesign that portion of the project.”

The heavy civil construction project involves reconstructing two miles of Country Club Road in a well-established area of the city. Lined with prominent, high-value homes and many businesses, the roadway is badly congested and sits atop several aging utilities that need to be replaced (and whose exact location wasn’t known until Sundt began investigating). Sundt’s scope includes widening and reconstructing the roadway with continuously reinforced concrete paving, replacing the water and sanitary sewer lines, and installing sidewalks, lighting, landscaping and a traffic roundabout.

Sundt will demolish this bridge at FM 3351 (a small, local roadway) over Interstate 10 and replace it with a new, 164-foot-long, single-span bridge.
Where others may only see a bridge, Sundt sees an opportunity to improve infrastructure while saving money. Near Fair Oaks, Texas (just north of San Antonio), Sundt is replacing this bridge at FM 3351 (a small, local roadway) over Interstate 10 with a new, 164-foot-long, single-span bridge. Sundt’s project team developed a value engineering proposal to replace the original structural steel girder design with precast concrete girders. The idea was approved by the Texas Department of Transportation and will provide significant cost savings.
Sundt’s scope consists of demolishing the existing bridge, widening the I-10 frontage roads, and widening FM 3351. Additional duties include earthwork, drainage, structures, walls, asphalt paving, signage, and striping. The project will be completed in March.

Sundt constructed the bridge’s 12, precast concrete arches with its own crews.
Texans traveling across the newly reconstructed West 7th Street Bridge in Fort Worth have more to marvel at than the 12, illuminated concrete arches that form the backbone of the structure’s one-of-a-kind design. The fact that Sundt completed the $24.1 million bridge construction project a month ahead of schedule – reopening it to travelers well in advance of the busy holiday season – is also drawing attention and praise. The 980-foot-long bridge spans the Trinity River and connects downtown Fort Worth to the city’s busy cultural district. It opened to traffic on October 9.
Sundt employed a number of innovative approaches to minimize traffic closures during the 23-month project. Chief among them was the decision to construct the 12 precast, post-tensioned concrete arches offsite (with Sundt’s own concrete construction crews) and then place them in pairs along either side of the old structure primarily at night. This approach allowed the bridge to remain open to traffic for the four months that it took to make and cure each 163-foot long, 300-ton arch. Once all of the arches were in place, the project team closed and demolished the old bridge and constructed the new one in its footprint.
The bridge’s grand opening celebration drew a large, festive crowd.
The bridge replaced an old, outdated structure. In addition to its attention-grabbing design, it features four vehicle travel lanes and two, 10-foot-wide pedestrian lanes to ease traffic flow, improve safety and support Fort Worth’s increasing interest in bicycling and walking.

Early next month, Sundt will break ground on the Hausman Road Improvement Project – the City of San Antonio’s first design-build roadway construction project. Hausman Road is a two-lane roadway that connects two major highways: Loop 1604 and Interstate 10. Sundt will widen the 3.4-mile stretch between the highways to four lanes, plus a center turn lane, and construct five new bridges. Also included in the contract are managing the extensive utility relocations, earthwork, construction of retaining walls, storm sewer, archeological and historic survey, environmental analysis and permitting, geotechnical work, right-of-way services and acquisitions, and public outreach.
The project team will break ground and begin moving utilities during the first week of December. The new and improved roadway is scheduled to be open in late 2015.
