Pinnacle Design/Build has successfully designed and constructed hundreds of thousands of square feet of retaining walls on transportation projects throughout the United States. Our commitment to safety, quality and schedule makes us one of the leading specialty geo-structural contractors to the transportation sector. We have completed projects in major airports, along interstate highways, on busy city streets and on remote US and state highways. No environment is too challenging.

Pinnacle Design/Build Transportation Project Profiles


		I-24 at Manson Pike, Murfreesboro, TN PROJECT FACTS: Wall Area = 57,000 SF; Max Ht = 28 FT CHALLENGE: The Tennessee Department of Transportation’s new interchange along Interstate 24 required retaining walls to support the ramps and bridge abutments. SOLUTION: Pinnacle Design/Build constructed segmental retaining walls to support the ramps and bridge abutments. VALUE: Pinnacle Design/Build constructed the completion of the retaining walls to allow the prime contractor to complete the overall project on time.

		I-10 at Picardy Lane, Baton Rouge, LA PROJECT FACTS: Wall Area = 230,000 SF; Max Ht = 33 FT CHALLENGE: The Louisiana Department of Transportation’s new interchange along Interstate 10 required retaining walls to support the ramps and bridge abutments. SOLUTION: Pinnacle Design/Build constructed segmental retaining walls to support the ramps and bridge abutments. VALUE: Pinnacle Design/Build constructed the completion of the retaining walls to allow the prime contractor to complete the overall project on time.

		Palisades Drive, Signal Mountain, TN PROJECT FACTS: Wall Area = 1,000 SF; Max Ht = 15 FT CHALLENGE: A century old, stacked stone retaining wall supporting Palisades Drive where it passes over a protected, environmentally sensitive creek was progressively failing. The failing wall put the busy roadway above and its passengers at risk. The wall had to be repaired without compromising the creek and with minimum impact to traffic. SOLUTION: Pinnacle Design/Build designed a gravity buttress wall using Redi-Rock™ large block units to stabilize the failing wall. Our crews carefully constructed the challenging repair without incident. VALUE: The Pinnacle Design/Build solution saved the town over $300,000 when compared to other solutions considered. In addition, the entire project (design to closeout) was completed in less than one month while keeping the Palisades Drive open to traffic.

		University of Virginia - North Grounds Connector, Charlottesville, VA PROJECT FACTS: Wall Area = 24,200 SF; Max Ht = 42 FT CHALLENGE: The University of Virginia needed a new roadway over a stream valley. SOLUTION: Pinnacle Design/Build constructed two back to back 42 ft tall MSE- panel retaining walls to support the elevated roadway. VALUE: The MSE retaining walls were constructed quickly and at a lower cost than conventional retaining wall options. The vertical retaining walls minimized the roadway’s footprint onto the stream valley.

		Consolidated Rental Car Facility (CONRAC), Hartsfield-Jackson Int. Airport, Atlanta, GA PROJECT FACTS: Wall Area = 2,200 SF; Max Ht = 29 FT CHALLENGE: The City of Atlanta required a new bridge and embankment at a key intersection inside the new CONRAC facility under construction at the Hartsfield-Jackson International Airport. SOLUTION: Pinnacle Design/Build constructed an MSE Panel retaining walls to form the abutments on both sides of the bridge. We also constructed precast and cast-in-place concrete coping to finish the top of the walls. VALUE: The MSE-Panel Retaining Wall supplied the structural support required while its architectural finish provided an aesthetically pleasing touch.

		Blue Ridge Parkway Landslide Repair, Spruce Pine, NC PROJECT FACTS: Wall Area = 5,000 SF; Max Ht = 22.5 FT CHALLENGE: Repair to the parkway at the several landslide locations. SOLUTION: Pinnacle Design/Build was part of a design team that utilized soil nailing, tiebacks and MSE retaining walls to stabilize the slide and support the reestablished roadway. VALUE: The solution of soil nailing and MSE retaining walls provided a high performance and reliable support system.

		UT DOT US 491, Monticello, UT PROJECT FACTS: Wall Area = 6,000 SF; Max Ht = 14 FT CHALLENGE: Utah DOT required a cost effective wall system to support widening of US Route 491 over a small ravine. Specifications called for a system that blended will with the natural environment of southeastern Utah. SOLUTION: Pinnacle Design/Build constructed a desert brown, split faced Segmental Retaining Wall (SRW) and heavy-duty cast-in-place concrete coping system. VALUE: The Pinnacle Design/Build solution was constructed quickly and cost effectively with minimum disruption to traffic and the surrounding desert.

		TN DOT SR 386, Hendersonville, TN PROJECT FACTS: Wall Area = 17,000 SF; Max Ht = 26 FT CHALLENGE: The Tennessee Department of Transportation's new interchange along State Route 386 required gracefully curving retaining walls to support the ramps and abutments on both ends of a new bridge. SOLUTION: Pinnacle Design/Build designed and constructed two smoothly curved segmental retaining walls (SRWs) to meet the DOT's requirements. VALUE: Pinnacle Design/Build rapidly completed the complex construction to meet the General Contractors accelerated schedule for bridge beam installation.
