Description: I-306C - DURHAM COUNTY LOCATION: I-85 over Club Boulevard
ITEM(S) OF INTEREST:The bridge over Club Boulevard includes a noisewall attached to the back of the barrier rail. Other municipalities are looking into doing something similar at other sites.
Observations and Points of Discussion:
There were several bolts missing from angles that secure the noisewall panels in place
Cracking observed on the barrier rail.
Some to this cracking is normal, and in this case the cracks happen to coincide with the embedded noisewall assembly pockets. Some pockets may have to be repaired.
The Bridge Maintenance Unit expressed concerns over the number of available panel suppliers and proprietary product issues.
These concerns may lead to the possibility of having to stockpile spare panels for possible future repairs to the noise wall.
