State Highway 16
SH 16 is the county’s defining north-south route.
It runs directly through Tilden and connects the county toward Atascosa County to the north and Live Oak County to the south.
TxDOT has completed or programmed several projects on SH 16 in and around Tilden.
The county’s Rural Transportation Improvement Program included pedestrian improvements along SH 16 from Water Street to SH 72 and from SH 72 to School Street.
For new drivers, SH 16 provides practice with:
Higher-speed traffic
Truck traffic
City-to-rural transitions
School-area awareness in Tilden
Highway intersections
Longer following distances
Rural side roads
SH 16 Frio River Bridge
TxDOT’s current McMullen County program includes replacement of the SH 16 bridge and approaches at the Frio River.
The project is programmed at approximately $12.5 million in the current Rural Transportation Improvement Program.
For students, bridge construction can introduce:
Narrowed lanes
Reduced speed limits
Construction vehicles
Temporary signs
Changed shoulders
Lane shifts
Students should follow current traffic controls rather than assume the bridge operates the same way it did on an earlier drive.
State Highway 72
SH 72 is the county’s primary east-west route through the Tilden area.
Current TxDOT programming includes seal coat and pavement marking projects on SH 72 from near SH 97 to SH 16 and from SH 16 toward the Live Oak County line.
For a beginning driver, SH 72 provides experience with:
Long rural stretches
Commercial traffic
Oilfield traffic
Highway intersections
Passing decisions
Night driving
Changes in pavement conditions
State Highway 97
SH 97 serves the western part of the McMullen County road network and connects with SH 72.
TxDOT’s current project program specifically identifies SH 97 as a project limit for SH 72 and FM 1582 work.
Students should treat intersections with SH 97 as high-speed rural intersections requiring careful gap judgment.
U.S. Highway 59
U.S. 59 crosses the southeastern part of McMullen County between the Live Oak and Duval county lines.
TxDOT’s current Rural Transportation Improvement Program includes U.S. 59 seal-coat and pavement-marking work across the McMullen County segment.
For new drivers, U.S. 59 introduces:
Regional freight traffic
Higher speeds
Long-distance travel
Large trucks
Highway intersections
Longer stopping distances
A student should develop strong rural-highway skills before using U.S. 59 for extended practice.
FM 99
FM 99 connects parts of the southeastern McMullen County road network.
TxDOT currently programs seal-coat and pavement-marking work on FM 99 from the Live Oak County line to SH 72.
Students should expect a rural highway environment with limited traffic controls and reduced nighttime lighting.
FM 791
FM 791 connects SH 16 toward the Atascosa County line.
Current TxDOT programming includes pavement and marking work on the route.
FM 1582
FM 1582 serves western McMullen County toward La Salle County.
Current TxDOT plans include maintenance from the La Salle County line to SH 97.
FM 3445
FM 3445 connects with SH 16 and is another locally important rural road.
TxDOT programmed seal coat and pavement markings on this route for FY 2026.
