Oak Hill Expressway (290 West and
71 West – The Y at Oak Hill)

Manchaca Expressway (45 SW)

The Green Mobility Challenge was a sustainable design competition that challenged Texas' most creative landscape architects, planners and engineers to propose better ways of constructing, operating and maintaining future transportation projects. By challenging teams to identify new methods, new materials and new ways of thinking, the Mobility Authority hopes to ensure transportation facilities in Central Texas are implemented and operated in a way that is environmentally responsible.

Two projects, the Oak Hill Expressway (US 290 West/SH 71 West) and the Manchaca Expressway (SH 45 Southwest), were selected for teams to submit conceptual sustainable elements.


Six teams representing 12 different companies and two universities competed in the finals event Tuesday, November 15, at the LCRA Redbud Center. Teams were challenged to submit sustainable design ideas on two particularly sensitive highway projects, the Manchaca Expressway (SH 45 SW) and the Oak Hill Expressway (U.S. 290/SH 71 West).


A team of 12 celebrity judges, including Federal Highway Administration Division Director Janice Brown, Austin City Council Member Chris Riley and Mobility Authority Board Chair Ray Wilkerson heard presentations from each team before awarding first place prizes of $15,000 each to the winners.

AECOM and a team made up of LJA Engineering, Coleman & Associates, Blanton & Associates and Construction Eco Services.
