  • TxDOT has issued a Record of Decision (ROD) for the North Houston Highway Improvement Project (NHHIP) and it is available for review. The ROD identifies the selected alternative and signifies the completion of the environmental review process.
  • The Selected Alternative includes construction of roadway improvements to add four managed express (MaX) lanes on I-45 from downtown Houston to Beltway 8 North, reroute I-45 to be parallel with I-10 on the north side of downtown Houston and parallel to US 59/I-69 on the east side of downtown Houston, realign sections of I-10 and US 59/I-69 in the downtown area to eliminate the current roadway reverse curves that limit capacity, and depress US 59/I-69 between I-10 and Spur 527 south of downtown to remove the problematic weaving sections. The proposed project also includes reconstruction of mainlanes and frontage roads; addition of bicycle and pedestrian realms along the streets that cross the freeways, including a 15- to 17-foot-wide pedestrian realm that will create a buffer between the bicycle and pedestrian traffic and the vehicular traffic; addition of sidewalks along frontage roads; and addition of pass-through lanes on I-10 that will separate traffic desiring to go to downtown from traffic destined to go through downtown.
  • The ROD documents selection of the Preferred Alternative described in the Final Environmental Impact Statement (EIS) as the alternative selected for implementation. It presents the basis for the decision, summarizes the mitigation measures that will be incorporated into the project, and provides responses to issues raised in comments received on the Final EIS. Although the ROD is the final step in the EIS process and results in a Selected Alternative, future changes and refinements to the project can still occur.
  • The ROD is written in English. If you need an interpreter or document translator because English is not your primary language or you have difficulty communicating effectively in English, one will be provided to you. If you have a disability and need assistance, special arrangements can be made to accommodate most needs. If you need interpretation or translation services or you are a person with a disability who requires an accommodation to review the ROD, please contact the TxDOT Director of Advanced Project Development at (713) 802-5070 no later than 4 p.m. CT, at least three business days before the date on which you would like to review the ROD. Please be aware that advance notice is required as some services and accommodations may require time for TxDOT to arrange.
