How do you build a roundabout within an existing intersection footprint?

WSDOT’s single-lane roundabouts are different. They are smaller and fit within the existing intersection footprint. These roundabouts feature mountable curbing, a traversable central island, and splitter islands that can be driven over by larger vehicles if needed.

WSDOT works to balance the needs of construction with keeping people moving. Roundabouts typically are built one component at a time. Traffic is guided around the construction area as each element is completed.

When constructing the roundabout, motorists can expect lane reductions, shifting of travel lanes in both directions, construction of outer curbing and island work on the main street with splitter island work on the side streets.

Roundabout construction is currently scheduled to take place from June through August 2023.
