Editor’s note: I incorrectly wrote that City of Tucson crews installed the sharrows along Fourth Avenue. It was actually the contractor hired by the city to perform the streetcar construction that placed the sharrows.
The recently added sharrows along Fourth Avenue are between one and two feet too close to the curb, violating national guidelines and the city’s own streetcar plans.
In most cases, the streetcar plans called for the center of the sharrow to be placed 12 feet from the curb, but measurements taken by Tucson Velo indicate the actual placement of the sharrows are between ten feet four inches and ten feet nine inches.
The Manual on Uniform Traffic Control Devices, which provides guidance on the use of traffic devices from the federal department of transportation, indicates that sharrows should be placed no less than 11 feet away from the curb when on-street parking is present.
The current positioning would place cyclists in a dangerous location, which could increase the likelihood of a dooring.
Streetcar construction manager Joe Chase did not return a phone call about the sharrow placement, but Tucson’s bicycle and pedestrian program manager Ann Chanecka said they were investigating the placement of the sharrows.
Plans indicate that parking along the north and south end of Fourth Avenue will be eliminated because the street is too narrow making the sharrow above more appropriate.
