TULSA COUNTY, Oklahoma - Heads up for drivers who use the Keystone Lake dam west of Tulsa to get to and from work.  

The U.S. Army Corps of Engineers will close Highway 151 in both directions for two weeks beginning Monday, August 22nd.

The Corps says workers will drill into the rock section of the dam, take core samples and send a camera down to check the bedrock and see if there are any maintenance concerns.

They plan to reopen the highway September 1st, if the test work is complete, weather permitting.
