Hardy Toll Road
|Maintained by HCTRA|
|Length:||21.6 mi (34.8 km)|
|Existed:||1988 – present|
The Hardy Toll Road runs from Interstate 610, near central Houston, to Interstate 45, north of Houston just below the Harris County line. The road generally parallels Interstate 45. The portion from I-610 to Crosstimbers Road is known as Spur 548, although this is unsigned. 
Construction on the toll road started in September 1984 and the entire road was complete by June 1988. The toll road runs 21.6 miles (34.8 km)  and costs $3.50 to drive its full length ($1.75 north of Beltway 8 and $1.75 south of Beltway 8). A four-mile (6 km) connecting road to the George Bush Intercontinental Airport requires a $1.25 toll. At Hardy North and South toll booths, a 20 cent discount applies to electronic EZ TAG users.
The road is named for nearby Hardy Street, which makes up the frontage roads for the toll road in two locations: (1) between Spring Railroad Yard and FM 1960 and (2) Greens Road to Crosstimbers Road.
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. Like other toll roads in the Houston area, the speed limit is 65 mph (105 km/h), even inside Beltway 8.
Future plans are to extend the toll road south an additional four miles (6 km) into downtown Houston (the northern most mile marker is 25, though the current road is only 21.6 miles (34.8 km) long). In November '07 the city of Houston gave approval for street closures required to construct the connections to the downtown freeway loop. Originally, construction was scheduled to start in August 2009 with completion sometime in 2011; however, this has been delayed. It is expected that the toll road will deviate from Hardy Street south of I-610 and follow Maury Street  to connect with the Eastex Freeway near I-10, as part of the ramp connections have already been built.
As of November 23, 2010, construction on the Hardy Toll Road Downtown connector has still not begun, with HCTRA's website reporting the project is still under design.
As the population of Montgomery County has grown quickly in recent years, the need for a northward extension is being evaluated. Originally, the plan was to construct the extension along the right of way for the railroad. However, recent growth in Oak Ridge North will require 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. No plans for construction have yet been formulated.
The following are the number of mainlanes in each direction, as of August 2008:
- 3 lanes each way between Interstate 610 and Beltway 8 (northbound exit/southbound entry)
- 2 lanes each way crossing over the Beltway 8 frontage roads
- 3 lanes each way between Beltway 8 (northbound entry/southbound exit) and FM 1960
- 2 lanes each way between FM 1960 and Hardy North Toll Plaza
- 3 lanes each way between Hardy North Toll Plaza and East Louetta Road
- 2 lanes each way between East Louetta Road and Interstate 45 (northern terminus)
