Additional key considerations

Segment 2

This segment will improve the I-45 mainlanes and frontage roads from I-10 north to I-610 and rebuild the I-45/I-610 interchange

Widen I-45 in this area to accommodate four MaX (Managed Express) lanes. The proposed roadway would include ten general purpose lanes (five in each direction), four MaX lanes (two in each direction), and two to three frontage road lanes in each direction.
- The MaX lanes would increase the High Occupancy Vehicle) space in the middle of the I-45 mainlanes from one lane to four. Only buses and vehicles with two or more people in them would be able to travel in the MaX lanes.
The proposed I-45 and I-610 frontage roads would be continuous at the I-45/I-610 interchange.
The mainlanes will be depressed between Cottage and N. Main streets, providing an opportunity to build a structural cap which could be funded and developed by others.
TxDOT is studying how to potentially reduce the roadway footprint of this project.
I-45 NHHIP proposes significant drainage improvements in accordance with new Atlas 14 standards issued by NOAA.
