The Grand Parkway is a planned 184 loop around the Greater Houston metropolitan area which currently has several sections currently open to traffic--from I-10 West to US 59 South and in Baytown on the east side of Houston region.  The total cost of this loop is currently estimated to be $3.7 billion.

A description of the Grand Parkway (from the current TxDOT/Area Counties discussions) is available in PDF format at this link.

Grand Parkway West will tie the Greater West Houston region's residential and commercial centers  together with a vital new north-south link.  Making up this link are:

• Section D, currently completed south from I-10 to the Westpark Toll Road (FM 1093), continuing south with frontage roads to Sugarland and US 59.
   
• Section E, a 15.2 mile section north from I-10 to US 290 is currently completing its environmental impact study with a record of decision expected in April, 2008.
  
  The current schedule (link to PDF) calls for design and right of way acquisition to begin in 2008 and construction to commence in January 2010.  While the schedule published by local and state agencies current call for completion in January 2011, it is likely this section can be completed and open to traffic in two-thirds that time, by January 2010.

• Section F2 connects the Grand Parkway to Interstate 45 north of Houston, and G connects to US 59 North (Eastex Freeway).

TxDOT and Harris and surrounding counties are negotiating terms and conditions leading up to a decision whereby one or the other undertakes the construction of the Grand Parkway.
