Here are the revised plans for a Gilman roundabout at the I80 interchange. The proposal is for a multilane design, but with curvature that limits speeds to no more than 25mph. This design was presented at the 3-19 Transportation Commission meeting.
To provide bike/ped access through the interchange, underpasses are proposed to run along the north end. This has not been indicated in the diagram (which currently shows at-grade crossings). Still to be decided: how to access the Class I path.
