I-95 SoftSound noise wall project completed

Easi-Set SoftSound licensed producer Smith-Midland Corporation provided design, panel/post layout drawings and fabrication of SoftSound noise wall panels and pre-stressed concrete posts for the VDOT I-95/Route 630 Interchange reconstruction and widening project located in Stafford, VA for Shirley Contracting.

46,800 square feet (308 pieces) of sound wall using New England Drystack finish on the highway side of the wall and Fuzzy Rake finish on the residential side was produced and delivered.

This project also used rubber form liner to provide VDOT with some aesthetic variation along I-95. The versatility of the precast concrete allowed this finish to be achieved at a reasonable cost.

For this project, SMC manufactured the longest pre-stressed sound wall column in the company’s history, measuring 67.5 feet. Hauling the long post required longer flatbed trailers than what was normally use. Two flatbed stretch trailers to haul these posts to the jobsite.

The project required a sound absorptive product be used on the highway face of the noise wall. SoftSound sound absorptive concrete which allows the sound wall to absorb traffic noise was the solution. SoftSound has an NRC (Noise Reduction Coefficient) of 0.80. This provides VDOT with a durable, long-lasting solution to reducing noise along its highways.
