The City of Houston is preparing for one of the biggest infrastructure projects in a generation. The project is called the North Houston Improvement Project (NHHIP) and it will reconstruct I-45 from Beltway 8 to Downtown. TxDOT’s goals for the project are to manage congestion, enhance safety and accommodate future growth.
NHHIP is 24 miles in length and will be separated into three segments. Segment 1 will include the widening of the freeway and additional new lanes from IH-610 N Loop and North Sam Houston Tollway. Segment 2 will widen and add new lanes of the portion of I-45 from IH-610 to downtown Houston. Segment 2 will also include a rebuild of the interchange between IH-45 and the IH-610 North Loop. Lastly, Segment 3 includes improvements to the segment of I-45 surrounding downtown Houston. Segment 3 includes the most expensive and all-encompassing improvements, as the entire 12 mile stretch of highway will be rebuilt (including four major interchanges).
The project in its entirety will take over ten years to complete. However, regional planning documents anticipate construction on Segment 3 beginning within the next two years. Segments 1 and 2 will begin construction in five to ten years. TxDOT is currently preparing the Final Environmental Impact Statement, which the public will have the chance to review for 30 days. Following the review period, TxDOT will reach a record of decision and start acquiring Right-of-Way before finally beginning construction.
