At the request of ES-CA, for the Placitas community, NMDOT (NM Dept. of Transportation) contracted with David Wilson of Souder, Miller & Associates to do a study of the safety issues at the new I-25/US 550 interchange. Mr. Wilson has produced a DRAFT safety review, which you can view here: I25_US550 Report Memo 09_24_14_MU. It discusses the various issues, and makes recommendations for improvement. The summary of recommendations can be found at the end, page 10. This is only a draft document, and could be modified before being submitted to DOT.
Bob Gorrell has highlighted areas of main interest in the report.
