NASHVILLE, TN (WSMV) - You may have already seen crews at work along the west side of I-440 installing a new noise wall just off 21st Avenue.

Lighting relocation, noise wall construction, shoulder paving and ramp work all start this week. However, traffic won't be impacted too much just yet.  

Lane and ramp closures will take place between 9 p.m. and 5 a.m.

The largest part of the project will start in the spring. That work consists of replacing the deteriorated concrete with asphalt and removing the grass median. The contractor plans to rubblize the existing concrete into gravel and use the material in the new roadway base.
