Project Schedule/Milestones

February 2023 – The full road closure of Merrill Avenue from Euclid Avenue to Stearman Drive commenced on Friday, February 10th for the purposes of installing a major storm drain facility at the Euclid Avenue street intersection. The contractor also completed temporary signal modifications during the month. However, recent rain events postponed additional construction activities until April 2023. 

April 2023 through June 2023 – The contractor is scheduled to install the storm drain across Merrill Avenue to approximately 600 feet south of the Euclid Avenue street intersection. 

July 2023 – The contractor is scheduled to repave and stripe the intersection in early July. The roadway is currently scheduled to reopen by Wednesday, July 5th, 2023.

Project Updates

Recent rain events have impacted the end date.

Technical Details

Construction activities along Merrill Avenue from Euclid Avenue to Grove Avenue will continue through 2023. However, construction activities after the reopening of Merrill Avenue are anticipated to only require intermittent lane closures rather than a full road closure.
