The North Houston Highway Improvement Project (NHHIP) is a planned reconstruction of I-45N, between Houston's downtown and the North Sam Houston Tollway, also known as Beltway 8, that includes segments of connecting freeways.
This project will improve I-45 from Beltway 8 to I-10, and reroute I-45 through the downtown Houston area along I-10 and US 59/I-69. Portions of I-10 and US 59/I-69 will be improved as well.
