Phase I also includes improvements to Loop 1604 to the north and south US 90, and a roundabout at Ray Ellison Boulevard. Phase II is west of Phase I, and its limits include Loop 1604 to west of SH 211. Key items include: Phase I is represented by three orange lines and Phase II is represented by a dotted purple line.

The US 90 Expansion project will be constructed in phases:

Phase I: I-410 to Loop 1604

Anticipated construction timeline: late 2025 through 2030

Length: 3.3 miles

Total project cost: $146 million

Improvements:

  • Reconstructing and widening US 90 from two to three 12-foot-wide mainlanes from I-410 to Loop 1604 with continuous two-to-three lane frontage roads in each direction.
  • Constructing a two-lane flyover ramp connecting westbound US 90 to northbound Loop 1604.
  • Constructing a roundabout at Ray Ellison Boulevard to improve safety and traffic flow.
  • Building auxiliary lanes in certain locations along the frontage roads to optimize traffic flow at key intersections.
