The Final Environmental Impact Statement (EIS) for the North Houston Highway Improvement Project is expected to be completed and available on this website in mid to late 2019. The Final EIS will identify the preferred alternative, provide responses to substantive comments received on the Draft EIS, summarize public involvement, and describe mitigation measures that will be incorporated into the proposed project.

As TxDOT completes preparation of the draft technical reports for the Final EIS, the draft reports are being made available to the public and TxDOT will accept comments on the draft reports. The comment period for each draft technical report ends no earlier than 30 days after it is posted on the project website. The draft technical reports are also available for review Monday through Friday between the hours of 8:00 a.m. and 5:00 p.m., excluding state holidays, at the TxDOT Houston District Office located at 7600 Washington Avenue, Houston, TX 77007. Please contact Terri Dedhia at (713) 802-5247 or Terri.Dedhia@txdot.gov to schedule an appointment to view the draft technical reports at the Houston District Office.

Comments on the draft technical reports may be submitted:
  -  On the Comments/Contact Us  page on this website
  -  In person at the TxDOT Houston District Office, 7600 Washington Avenue, Houston, TX 77007
  -  By mail to: TxDOT Houston District Office, Director of Project Development, P.O. 1386, Houston, TX 77251-1386
  -  By email to: HOU-piowebmail@txdot.gov

A draft technical report will remain on the website after the close of the comment period. If TxDOT makes a change to its analysis as a result of a comment on a draft technical report, TxDOT will explain the change in the response to comments in the Final EIS.

Proposed Recommended Alternative
In response to comments received on the Draft EIS and based on further engineering and environmental evaluation, changes are proposed to the design of the Proposed Recommended Alternative that was presented at the Public Hearing in May 2017. These and other design changes that were presented at the Public Hearing, such as the locations of storm water detention basins, are being evaluated and documented in the Final EIS and associated technical reports.

The Segment 1 design has not changed since the May 2017 Public Hearing. The proposed changes are in Segment 2 and Segment 3 of the project. The revised conceptual roadway layouts and typical sections can be viewed at the links below.

Proposed Recommended Alternative
Conceptual Roadway Layouts and Typical Sections (as of May 2018)

SEGMENT 1 (May 2017)
   Segment 1: I-610 to Tidwell Road Plan and Profile
   Segment 1: Tidwell Road to Shepherd Drive Plan and Profile
   Segment 1: Shepherd Drive to West Road Plan and Profile
   Segment 1: West Road to Beltway 8 Plan and Profile

SEGMENT 2 (May 2018)
   Segment 2: I-45 north of I-10 to I-610 Plan and Profile
   Segment 2: I-610 Interchange Plan and Profile

SEGMENT 3 (May 2018)
   Segment 3: Downtown Loop Overall Plan View

Conceptual Layouts and Typical Sections for the Proposed Recommended Alternative are Preliminary and Subject to Change



The Texas Department of Transportation, in cooperation with the Federal Highway Administration (FHWA), initiated the National Environmental Policy Act (NEPA) process for highway improvements in the north Houston area. The North Houston Highway Improvement Project involves evaluation of the I-45 North corridor from near downtown Houston to Beltway 8 North, Beltway 8 North from I-45 North to the Hardy Toll Road, the Hardy Toll Road from I-610 North Loop to Beltway 8 North, I-610 North Loop from I-45 North to the Hardy Toll Road, and portions of I-10 and US 59 near downtown Houston.

Prior to December 16, 2014, the FHWA reviewed and approved documents prepared under the NEPA; however, on December 16, 2014, the Texas Department of Transportation assumed responsibility from FHWA for reviewing and approving certain assigned NEPA environmental documents. The Texas Department of Transportation will approve the North Houston Highway Improvement Project Draft and Final Environmental Impact Statements.

The primary objective of the NEPA evaluation is to assess the needs of the project area and evaluate possible alternatives, including a no build alternative. Environment impacts will be further evaluated for those recommended alternatives that meet the need for and purpose of the project in order to select a preferred alternative. The Environmental Impact Statement process will include participation and involvement of the public, elected officials, cooperating agencies, and other interested parties.
