The Highway 69 Hole

Wave action caused a "void" under the Highway 69 bridge. This project this week was aimed at keeping that from turning into a bigger problem. 

Motorists on the Warrenton Causeway had a detour at the bridge this week. 

Those who glanced over in the southbound lanes saw an enormous hole, 10-feet deep. ALDOT officials said there was a "void" in the material adjacent to the bridge abutment caused by wave action from the lake under the bridge. 

"Over time, wave action has washed out material, creating a void under the asphalt roadway at the end of the bridge and leaving the pavement susceptible to damage and eventual failure," said ALDOT spokesman Seth Burkett. "The repair includes insertion of steel plates, backfilling with riprap stone, pouring a new concrete slab and repaving the asphalt."

It was hoped that the repairs would be finished late this week. 

The metal plates interlock to create a wall of steel, according to ALDOT division engineer Curtis Vincent. It should keep wave action from ever damaging that section of roadway again.

"It should be there a very long time," Vincent said.
