Sign up to receive emailed construction updates. 

Construction Update as of 6/11/19: The first concrete placement on the east side of Franklin Road was Saturday, June 1st. The next concrete placement is expected to begin as early as June 17th. Crews will place concrete on North Cole Road and the west side of Franklin Road at that time.

After asphalt paving on the east side of Cole Road from McMullen south to the I-84 ramp is complete there will be a traffic shift on Wednesday, June 12th.  Traffic from McMullen to the I-84 ramp will shift onto the new asphalt on the east side of the road. This will allow for the crews to begin the improvements on the west side of the road. 

Asphalt paving from McMullen to Franklin Road is expected to start late June.

Cole Road between Franklin Road and Barrister Drive will be closed from May 17th to July 12th as part of the Cole Road, I-84 to Franklin project.

Changeable message boards have been placed in advance of all four legs of the intersection to notify drivers of this upcoming change. Businesses will remain open, but some access points have changed. Signs will be present to help drivers find the appropriate routes to businesses during this closure. The map directly below illustrates some of the alternative routes motorists may consider using during this time.

Why close the road?

An evaluation was made of the amount of space available in the intersection while still maintaining travel lanes on Franklin Road, and it was determined there was not adequate room to safely place equipment and pour the concrete paving on the northern portion of Franklin Road and North Cole Road. If North Cole had remained open, traffic on Franklin Road would have been significantly impacted and the intersection would experience substantial delays. Therefore, in order to maintain a safe work zone and to keep traffic on Franklin Road moving, the road needed to close. North Cole Road was always expected to close for a period of time to allow for work on the railroad crossing, and in order to prevent multiple closures, the decision was made to keep the road closed for longer in order to build the improvements for North Cole and the northern side of Franklin. Closing the road also has the added benefit of speeding up work in this area, thereby saving time in the overall construction schedule

Construction Update as of 5/17/19:

Cole Road between Franklin and Barrister closed the morning of May 17th at 6:00 AM. The railroad will work on the crossing for the first week of the closure. Then the contractor will begin preparing and placing concrete on the north side of the intersection.

Curb is nearly complete on the east side of Cole Road from the bridge to the south. Sidewalk in this area is also being placed. Curb is being placed on the north east side of Franklin.

Previous Traffic Updates:

Traffic on Franklin Road and Cole Road has been reduced to one lane in each direction as of March 26th. Crews are working on storm drain installation as well as installing sewer on Franklin Road. Most of the walls on the east side of Cole Road have been built. Crews are working on placing 3/4" material on the east side of Cole Road.

Paving on McMullen is nearly complete and the bottom lift of asphalt is in place. The new signal is open!

Traffic on Franklin Road was shifted to the south side on the night of Monday, March 25th.  The new traffic pattern includes one lane in each direction on Franklin Road including left turn lanes at the intersection. This traffic pattern is expected to cause delays, motorists are encouraged to seek alternative routes when possible.

The traffic shift on Franklin Road has been postponed until the night of Monday, March 25th. Work will begin at 8:00 PM and will last until 6:00 AM. Traffic will be moved to the south side of Franklin Road to allow for work to begin on the north side of the road. There will be one eastbound lane, one westbound lane and left turn lanes as part of the new configuration. Pedestrians should use the east side of Cole Road north of the intersection and the south side of Franklin Road. This traffic shift will put the project into Phase 2 of construction. The traffic shift was previously planned for the night of March 18th.

Work on the north side of Franklin Road is expected to begin as early as the week of March 25th. In preparation of that work, there has been ongoing utility relocations with temporary lane restrictions. This schedule is weather dependent and subject to change.

Traffic was shifted to the west side of Cole Road and work is underway on the east side of Cole. McMullen on the east side is closed to all but local traffic as part of the work to realign that intersection.

What Can Neighbors and Commuters Expect?

  • Work is anticipated to occur between 7 a.m. and 7 p.m. Night work and weekend work is expected.
  • Work will include, but not be limited to, general construction noise, dust, equipment backup alarms, and ground vibration.
  • Access to businesses will remain open at all times, although ingress and egress may be shifted to accommodate construction. If business access will be impacted, the contractor will coordinate with adjacent businesses.
