A couple of major roads in Odessa and Midland will be under construction.
Crews will resurface West Loop 338 between Yukon Road and Kermit Highway in Odessa and Loop 250 North between Garfield Street and Big Spring Street in Midland.
Lanes and temporary ramps will be closed.
The speed limit will drop down to 60 miles an hour in Odessa and 50 in midland.
The Loop 250 project will also have a width restriction of eleven feet.
That project will be done in stages with repairs made this fall, and final surface being put down in the spring.
Crews are expected to be finished with Loop 338 by March 2016.
Drivers are urged to find alternate routes until work is completed, and to obey all work zone signs and all flag crew members if they must travel through the work zone.
