Infamous St. Johns Avenue S-curve to get reflective road markers

Infamous St. Johns Avenue S-curve to get reflective road markers
A one-third mile portion of St. Johns Avenue will receive solar reflective pavement markers this month.

A Florida Department of Transportation safety improvement project on St. Johns Avenue is being undertaken during the month of July between Greenwood and Van Wert Avenues.

Internally Illuminated Retroreflective Pavement Markers (IIRPMs), also known as “solar RPMs” are an innovative product being piloted on a section of S.R. 211 (St. Johns Avenue) to determine their effectiveness in reducing the lane departure crashes on an urban “S” curve. 

According to the FDOT, the markers will be embedded into the roadway to enhance delineation and driver awareness, especially in low visibility.

The $90,000 project, under contract with Petticoat-Schmitt Civil Contractors, Inc., may require some daytime closures during non-peak hours. The project will be done in three sections over approximately one-third of a mile beginning with Greenwood Avenue north to Montgomery Place; Montgomery to Shadowlawn Street, and then Shadowlawn to Van Wert Avenue at Boone Park. 

That stretch of St. Johns Avenue has seen its share of vehicular incidents. In recent years, several drivers racing through the curve have lost control and, in one incident, terminated the trip at a brick wall on the corner of St. Johns Avenue and Glendale Street.

If the pilot shows that the IIRPMs are an effective countermeasure, other locations may be eligible for IIRMs in the future. Any additional installations would require a safety study and approval, according to Bianca Speights, FDOT public information officer.
