The heavily traveled TX-183 corridor is a direct east/west route between Dallas-Fort Worth and their International Airport. The corridor also has vital utilities along the right-of-way, including those serving the airport. The proposed sound wall location would not allow for drilled shaft foundations, which are required for heavy precast concrete sound walls.
Lightweight PVC AIL Sound Walls recommended for tight, shallow site
Southgate Mobility Partners, a joint venture created for the massive $847-million Midtown Express Project, needed a lightweight sound wall system that would be installed with a continuous shallow foundation. AIL Sound Walls were recommended by joint venture partner, Keiwit, based on their similar project with us on the Houston MetroRail expansion.
With sidewalks and private yards on either side, the foundation area’s width was also very limited. We provided foundation options with minimal impact to the utilities and adjacent property owners.
Grade changes, angles, gates, custom color panels and posts
This project really demonstrated the complete versatility of our lightweight PVC sound barrier wall system. The sound wall had several different sections with grade changes—it butted up against sidewalks, it angled around utility boxes and it included multiple gates.
Plus, TxDOT and the local community had selected a unique color aesthetic for the 183 corridor and wanted a system to match. They worked with our design and manufacturing teams to develop an aesthetic scheme with the colors they were looking for and they requested a wood grain texture. These design options were invaluable to TxDOT and the community.
‘One Team’ approach for a successful outcome
The project was also a perfect example of our ‘One Team’ approach. As the leader in sound wall technology, AIL Sound Walls quickly involved our AIL Group sister company, Big R Bridge, whose team already had extensive experience with TxDOT projects.
Big R’s Aaron Clauson worked very closely with the joint venture’s engineering team and AIL Sound Walls to lay out the wall properly. We ensured a streamlined manufacturing process on the custom panel and post colors. Very positive feedback was received from the customer and we’ve already heard from TxDOT about lightweight sound barrier walls for other projects in high traffic areas with extensive underground utilities.
