Notice of Availability - SH 99 Grand Parkway Segment B


This notice advises the public of a Record of Decision (ROD) for the construction on the Grand Parkway State Highway (SH) 99 Segment B project from SH 288 to IH 45 South in Brazoria and Galveston Counties, Texas. The ROD, which explains the Selected Alternative and signifies the completion of the environmental process, is also available for public review.


The project includes:
  • Construction of an approximately 28.6-mile alignment, on new location, from SH 288 to I-45 South through Brazoria and Galveston Counties.
  • The SH 99 Segment B would be constructed as a four-lane, controlled-access tollway facility, consisting of two lanes in each direction within a 400-foot-wide right of way (ROW) and auxiliary lanes between on-ramps and off-ramps, where appropriate.
  • The Selected Alternative would require approximately 1,072 acres of new ROW.

To avoid noise impacts that may result from future development adjacent to a proposed highway project, the ROD includes a traffic noise analysis with predicted noise impact contours for currently undeveloped areas. These impact contours are general guides intended to assist local planning officials and developers plan and construct new activities in locations that would not result in traffic noise impacts.

On the date of approval and clearance of a ROD for a proposed highway project, which in this case was Nov. 30, 2016, TxDOT is no longer responsible for providing noise abatement for new development.

A digital version of the signed ROD is available through the web link below or by request by contacting the Houston District office.
