The Fluor-led joint venture used the design-build approach to deliver Phase 4 of the SH 161 toll road for NTTA. The NTTA will operate and maintain the toll road.
The multi-level interchange at IH 20 includes a three-leg, four-level interchange with four direct connector ramps. At the IH 30 interchange, the improvements comprise a fully directional, five-level interchange with eight direct connector ramps consisting of either one or two lanes.
Three direct connector ramps are depressed. Substantial completion of the multi-level interchanges at IH 20 and IH 30 and the main lanes occurred in the fourth quarter of 2012.
