Recently, a federal regulation was passed, requiring that all street signs now be in upper and lower case. Many of those signs were capitalized nationwide, and the Department of Transportation in Washington D.C. determined that it's easier to read the new signs.
In the Permian Basin, the City of Midland is making changes to their street signs.
"As it becomes time for a sign to be replaced, we go ahead and make sure it meets the new regulations," Eric Johnson of the City of Midland told Big 2.
The signs are being changed as they wear out. Because of that, the cost hasn't been too unexpectedly high for cities.
