The Transportation Board meeting in White Rock on Thursday was taken up with a presentation and discussion of how to upgrade/modify NM-4 through White Rock to make it more people-friendly in light of County plans to develop both sides of the highway. Many in the community, and apparently in DOE and NNSA as well, continue to be skeptical of roundabouts. So the White Rock Implementation Committee downplayed their use, even though no one seems to know why they should not be used. Indeed, the Transportation Board members supported their use here. So here we go again--round and round in the same circles of questioning, explanation, and skepticism.
There is plenty of information on roundabout safety out there. Here is an FHWA link. Kinda surprising that we have to keep going "round and round" with these discussions.
