Primary Local Driving Topic: Highway, Frontage Road and Causeway Transitions
One of the most useful local skills for a Cameron County beginning driver is learning to move between different types of roadways without making rushed decisions.
The county's transportation network includes interstate corridors, U.S. highways, state highways, FM roads, city streets and the South Padre Island causeway approach. A student may encounter all of these during normal regional travel.
Plan lane changes early
If you know you need an exit, identify the correct lane well before reaching the interchange. Avoid crossing several lanes at the last second.
Watch entrance and exit ramps
Highway ramps create situations where vehicles are entering, exiting and changing speed in a relatively small area. Check mirrors and blind spots before changing lanes.
Do not assume the road will stay the same
Transportation projects can change lane configurations, turning movements, shoulders and access points. Cameron County currently has transportation projects involving corridors such as Old Alice Road, and TxDOT continues to plan improvements throughout the region.
Treat the causeway approach as a planned route
For South Padre Island travel, FM 510, SH 100 and SH 48 feed traffic toward the Queen Isabella Memorial Causeway. Because the causeway is the only roadway access to the island, drivers should know their route before reaching the final approach.
