A four-mile (6 km) connecting road to the George Bush Intercontinental Airport requires a $1.20 toll.

A large portion of the southern segment resembles Austin's Mopac Expressway in that an active line of the Union Pacific railroad runs along its median.

In November 2007 the city of Houston gave approval for street closures required to construct the connections to the downtown freeway loop.

However, recent growth in Oak Ridge North requires that the Hardy Toll Road extension deviate from this right-of-way in places.

Feasibility studies have evaluated possible routes between FM 1314 and the San Jacinto River, with the northern terminus planned to be at Loop 336.
