Road Project Update (Updated: 11/28/23)

Due to this construction project, traffic will be reduced to one lane between 9:00 a.m. to 3:00 p.m. during the week of November 27th. The contractor is utilizing temporary traffic signals to safely move traffic through the work zone. Occasionally the contractor may have to stop traffic temporarily to drop large trees that are being cleared between Windsor Parkway and NW 61st Avenue. Please expect delays. Per project specifications, trees are to be removed from October through March. Some of the trees are being removed because of the health of the trees. A trail will be installed providing an extension. 

Road construction will begin in the Spring of 2024. Please check this page for the public to attend a future project kickoff meeting in the spring of 2024 prior to the start of construction.
