US-1 traffic study and LOS methodology
Summary
Staff went project-by-project through all 47 priorities for easing U.S. 1 congestion, from a Keyswide bike-ped master plan grant expected in June to a pedestrian bridge from Stock Island to Key West being re-examined by FDOT. Two transit projects were shelved and the countywide traffic-flow analysis is getting cost estimates before the county commits money.

Board of County Commissioners - Oct 21, 2026
The county's biennial US-1 travel time study shows average speeds of 46.2 mph — just above the 45 mph threshold that would freeze development. Citizen groups and 24 organizations say the 35-year-old methodology inflates speeds by excluding construction, school zone, and bridge delays, and want an independent review and a 2028 next study. The board accepted the study with the most conservative data and will explore a consultant review.

The county is updating how it measures traffic on U.S. 1, using travel-time runs in late February and March and excluding construction delays. It sounds technical, but it determines how much development the corridor can absorb.
