Some drivers on the East End are now facing a year and a half of road re-construction.

News 12 Long Island has learned the Riverside traffic circle is getting a $5 million upgrade.

The upgrade includes expanding the one-lane roundabout into two lanes.

Suffolk County Executive Steve Bellone says the upgrade will ease congestion and improve commuter safety.

Construction will be done in eight separate phases to minimize traffic disruptions.

The entire project is expected to be completed by December of next year.
