Detailed Description

The following is a daily description of work activities. This order of work could be adjusted at any time to accommodate weather or unforeseen circumstances.

Time of Work

9:00 am to 3:30 pm: These are hours of work requiring lane closures for most days of work with significant impacts to traffic, additional hours of work may extend from 7am to 5pm.

Traffic Control

There will be various work zones set up throughout the project. Flaggers and uniformed police officers will be stationed throughout the project to assist with traffic control. There will not be enough room for u-turns in the work zones so drivers wanting to turn around will need to travel to the next traffic signal outside of the work zone.

Intersection and Driveway Access

Most of the time, driveways and intersections will remain open. Depending on the location, flaggers may be stationed to assist with driveway access. There will be short duration closures when work is occurring at driveways or intersections. These closures are expected to last no longer than 15 minutes.

Bus Routes

Bus routes are open during construction. However, there are times where bus stops in the work zones may need to be moved or closed due to proximity of the construction work.

Project Funding

The project is fully funded by a National Highway Performance Program federal grant. The cost for this project is approximately $1.8 million.
