While there is still a fair amount of work to complete on landscaping, street lighting, fencing, permanent striping, and cleanup, the major road reconstruction and paving is complete at Garden Corner Curves and the road has reopened.

Thank you to everyone for bearing with the construction noise and for your patience while you had to use alternate routes during the road closure.

Please note: the project is not fully completed, construction will continue along the corridor, which may include flaggers and potential delays.

This will be the last weekly project update showing the construction progress on the website. However, the project team is planning a reopening event to celebrate project completion on November 20th between 9:30am – 12:00pm. Mark your calendars and stay tuned for more details!

 

 

The road is CLOSED - but check here for weekly project updates including photos that will provide a glimpse of the progress being made behind the scenes.

October 14th, 2021 - Project Update

The contractor has paved the roadway through the Garden Corner Curves. They were scheduled to pave the pathway alongside the road this week, but the cold and wet weather hinders good paving results, so pathway paving is now scheduled to be completed early next week (weather permitting).

Please note the road will still remain closed after the paving is complete until the crew stripes the pavement and finishes up some additional work before reopening. Striping, street light work, stormwater facility planting, and landscape installation is planned next week.

We hope to reopen the road on Friday afternoon, October 22nd (weather permitting).

We have also begun to plan the reopening event to celebrate the improvements throughout the corridor. Stay tuned for more details in the weeks to come.
