FINAL ACCEPTED ON MARCH 10, 2021

This project is installing Dynamic Envelopes at multiple railroad crossings in Hillsborough County.

Locations of crossing:

• US 41 in Lutz
• Fowler Avenue (SR 582)
• Busch Boulevard (SR 580)
• Nebraska Avenue (US 41)
• Florida Avenue (US 41 B)
• 56th Street (SR 583)
• Hillsborough Avenue (US 92)
• 40th Street (SR 599)
• MLK Boulevard (SR 574) - two locations
• Causeway Boulevard (SR 676)
• US 41 in Palm River
• US 41 in Gibsonton
• US 41 in Apollo Beach

Dynamic envelopes are roadway markings used to increase safe stopping behavior and safety for both vehicular and pedestrian traffic at grade rail crossings. These markings indicate the clearance needed for trains to safely pass. 

By keeping vehicles outside of the dynamic envelopes, fewer vehicles will be stopped too close to or actually on the tracks, thereby reducing the danger to vehicles, occupants, train crews, passengers and bystanders.

The goal is to positively influence driver behavior and reduce the number of incidents and injuries sustained at rail crossings.

The project is underway and all of the above locations should be completed in the spring 2021.
