Moving the ramp to the west will require eliminating the eastbound Midway bypass. This bypass was providing new access not currently available. Braiding the SB to WB DNT Ramp and the WB Midway Exit Ramp Grade separate the westbound vehicles entering IH 635 from the DNT and the westbound vehicles exiting to Midway by constructing braided ramps. IH 635 ramp will go over Welch while the WB exit to Midway will go under Welch. The NTTA is considering closing the NB to WB loop ramp.
Primary reason is to more easily accommodate three lanes on the NB DNT through the interchange.
Accept Braiding the EB Entrance Ramps from the DNT with the EB Exit to Preston Eliminate weave on mainlanes by braiding the EB entrance from the DNT and EB exit to Preston. The Preston ramp and DNT ramp would then pass under Montfort. The geometric design needs to be developed to determine if this recommendation is feasible. Traffic volumes on the EB entrance from Preston and WB exit to Preston may require 2 lane ramps. Auxiliary lane between WB entrance from Preston and the WB exit to the DNT may improve traffic operations.
