​12th Street Corridor Improvement Project 


Project Overview

The project includes improvements along 6.5 miles of 12th Street, including 120 new poles, improved traffic detection systems and signal coordination, and upgraded pedestrian features and curb ramps throughout the corridor.

Complete signal replacements will be done at the following intersections with East and West 12th Street:

Weschler Avenue, Raspberry Street, Cascade Street, Plum Street, Liberty Street, Cherry Street, Chestnut Street, Myrtle Street, Sassafras Street, Peach Street, State Street, French Street, Holland Street, German Street, Parade Street, Wallace Street, Ash Street, Reed Street, and Wayne Street.

Modifications, including retimings, will be done at the following intersections with West 12th Street:

Interstate 79 northbound on-ramp, Lincoln Avenue, and Greengarden Road.

This project also includes the installation of two electronic message boards, one on I-79 northbound before the exits for 26th Street and 12th Street and the other on Route 290 before the intersection with 12th Street. The large IntelligentTransportation System (ITS) dynamic message signs will be used to alert motorist of travel times to key destinations, as well as crash and weather-related incidents.

Onsite work is expected to start on April 4, 2022, weather permitting, and to be completed in November 2022. 

The bridge is an ancillary project to the Bayfront Parkway Central Corridor Improvement Projectwhich is expected to get underway next year. The 12th Street upgrades will allow for safer and more efficient traffic flow through that area, which will be used as a detour during different portions of the Bayfront project. It will also improve safety for pedestrians and cyclists.

The Bayfront Parkway project is focused on improving pedestrian, bicycle, and traffic access at Sassafras Street Extension, State Street, and Holland Street. 



Drivers should anticipate delays along the 12th Street Corridor starting the week of July 25 as work continues to update the traffic signals at several intersections.

Power Contracting Company is schedule to begin installing the overhead portion of the traffic signals, known as the mast arms, at many of the intersections along the corridor.

Work is expected to start July 25, 2022, weather permitting and will continue for several weeks.

During installation of the mast arms, traffic will be stopped at the intersection for approximately five to 10 minutes. Drivers should anticipate delays throughout the day and are encouraged to take a different route during the daytime hours, when possible.
