Primary Nolan County Driving Topic: Long-Term I-20 Improvements Through Sweetwater
TxDOT is currently studying major long-term improvements to approximately 10 miles of I-20 through Sweetwater from State Loop 170 to near FM 1856.
TxDOT states that the goals are to improve safety, bring the corridor up to current design standards, improve mobility, and support economic development.
This is a current study.
For student drivers, the planning is important because I-20 through Sweetwater may eventually include changes involving:
Main lanes
Ramps
Interchanges
Frontage roads
Lane configuration
Access points
Read Current Signs
Students should never assume a ramp or frontage-road movement will remain unchanged.
Choose Lanes Early
Highway decisions should be made before the student reaches the interchange.
Avoid Last-Second Exits
If the student misses an exit, continue safely and use the next legal route.
