TX · SELECTED CORRIDORS
Texas road conditions & weather — the routes we actually cover.
Browse 3 curated corridors that cross Texas. Compare arrival-time weather, then use TxDOT DriveTexas for the current road restrictions RoadAheadNow cannot confirm.
OFFICIAL ROAD SOURCE
TxDOT DriveTexas
Use the official source for current Texas restrictions, incidents and road information. A weather forecast or missing route record is never treated as a road-open confirmation.
Coverage on this page: 3 catalogue corridors only. NWS weather is checked on request at selected checkpoints. No live state road feed is counted as integrated here; official links remain separate checks.
I-35E / I-35
~195 miCentral Texas I-35
Dallas to Austin
The Dallas–Austin corridor runs through a busy central Texas spine where thunderstorms, heat and flash flooding can matter at different points in the drive. Use the weather timeline for timing and DriveTexas for current road conditions.

I-35
~80 miCentral Texas I-35
Austin to San Antonio
The Austin–San Antonio corridor is short enough that thunderstorm, heat and flash-flood conditions can affect only part of the trip. Arrival-time checkpoints keep that weather context separate from the heavy traffic this baseline does not measure.
6 checkpoints~1h 25m baseline1 state
I-45
~240 miTexas I-45
Houston to Dallas
I-45 connects two major Texas metros through a long inland corridor where thunderstorms, heat and heavy rain can matter well away from either endpoint. Use the checkpoint timeline for weather and DriveTexas for current road restrictions.
