Design Considerations for US 50 / SR28 Trumpet Interchange

by Robert W. Byren, TESA Tech Team

We suggest that a “trumpet” interchange at the Spooner Summit interchange, with SR20 passing under US 50, may be a better alternative to the roundabout.  It is technically feasible at this location  and provides several advantages over the 3-leg large-scale roundabout proposed in the CMP:

·      Free-flow of traffic on US 50

·      Improved automobile and truck turn movements in all directions, minimizing wait time

·      No weaving (lane change) movements, thus avoiding certain accident types

·      Improved bicycle safety by eliminating crossing movements

·      Improved evacuation operations with no roadway reconfiguration

East Shore residents have been asking NDOT for serious modeling and simulation to demonstrate safety benefits of CMP. Here is their response.

What are your thoughts on the NDOT/TRPA plans for a road diet on US HWY 50?
