Closures Planned for Three September Weekends on Hwy. 321 Bridge

A contractor for the N.C. Department of Transportation has scheduled three weekend closures on U.S. Highway 321 over the Catawba River this month. The closures will allow crews to complete a rehabilitation project on the U.S. 321 South bridge.

The closures will take place on the weekends of Friday, September 9 through Monday, September 12; Friday, September 16 through Monday, September 19; and Friday, September 23 through Monday, September 26. The closures in each case will run from 7 p.m. on Friday through 7 a.m. on Monday.

Traffic traveling in both directions will be placed in a one-lane pattern on the U.S. 321 North bridge over the lake. Drivers should anticipate delays going north or south as vehicles merge from two lanes into one lane. Closing the bridge is necessary for contract crews to safely perform the work while traffic safely crosses between Caldwell and Catawba counties.

Crews from N.H.M. Construction will remove the existing surface and replace it with a latex modified concrete. The operations are part of a $1.9 million bridge preservation project that will extend the service life of the bridge.

A temporary crossover has been constructed to facilitate the upcoming rehabilitation. Crews have already completed about 75% of the necessary work under the bridge, including a majority of beam repairs, bolt repairs, and painting. The contract currently calls for completion of all work by November 30.

Transportation officials remind drivers to merge early, obey all posted traffic signs, and exercise caution. For real-time travel information, visit or follow NCDOT on social media.
