Project Description: This is a safety and operational improvement project at the intersection of Hawthorne Avenue and Oglethorpe Avenue. Improvements include:
Replacing the existing span wire signals with new mast arm signals.
Removing the concrete island located on the northwest quadrant and the "slip" right-turn lane. A dedicated right-turn lane will remain, but speeds through the intersection will be reduced by removal of the slip-lane.
Reestablish high visibility crosswalks, ADA ramps and wider sidewalks at the intersection.
Rebuild the intersection include flashing yellow arrow signal heads for the left turn movements and back plates on all signal heads to improve visibility.
Permissive left turn prohibitions on movements with high crash experience during peak hour traffic.
Restriping the pavement to improve sight distance for the northbound and southbound lanes.
Restriping the pavement to include one receiving lane for northbound traffic and creating a short two-way left turn lane to accommodate midblock left turns into the YMCA and other driveways along Hawthorne Avenue north of Oglethorpe Avenue.
Project Goals and Objectives: Improve the Level of Service during peak traffic hours by reducing delays, reducing speeds through the intersection, upgrading the existing traffic signal system, and installing/replacing sidewalks within the project limits. Provide a safer intersection for all users.
