Segment 2
This visualization shows the proposed I-45 from the I-10/Quitman Street area including the  

I-610 interchange, moving southbound to northbound. An area of I-45 between Main and Cottage streets is proposed to be depressed. The structural cap on top could be developed by parties other than TxDOT into a public space.  

In this area, the I-45 North Houston Highway Improvement Project, or NHHIP, would widen the roadway to accommodate four lanes known as Max lanes. The roadway would have five general purpose lanes in each direction, with full-width shoulders added. In the middle would be two Max lanes in each direction, operating 24 hours a day, seven days a week carrying High Occupancy Vehicle, or HOV, traffic. 

Currently, the limited HOV system in this area consists of one reversible lane, which takes traffic inbound in the mornings and outbound in the evenings. Along the frontage roads, bicycle-pedestrian features would also be added. 

At the I-610 interchange, continuous frontage roads would be built along both I-45 and I-610. The current left exits to the direct connectors at the interchange would be replaced by exits on the right side of the roadway.
