Also, many maps do not show the correct route for RI 51. Generally, maps which show RI 51 at all show it starting at RI 37 on Natick Avenue, then heading along Natick Avenue and Phenix Avenue, ending at RI 12. This route is incorrect according to RIDOT whose pavement management log shows RI 51 taking the route shown above in the "Route" section; it comes close to RI 37 but does not intersect it. Please see: Scan of RI 51 from the RIDOT Pavement Log (PDF) Also of note is that there is no RI 51 signage on RI 51 itself, though there are two blank sign posts that may have carried RI 51 shields at some point. According to RIDOT, the towns through which RI 51 runs requested that the signs be removed to give them time to prepare for the increase in traffic brought by a numbered route. There are also some trailblazer assemblies along RI 5 and RI 12. | valign="top"|right |
