Newcastle drivers should be aware of a few upcoming traffic impacts connected to various construction projects.

First, Lakemont Boulevard Southeast will be closed between Forest Drive Southeast and 155th Avenue Southeast starting at 5 a.m. June 20. It will reopen at 5 a.m. June 22 with alternating one-way traffic.

Drivers will be detoured onto Forest Drive Southeast, Coal Creek Parkway or Newcastle Golf Club Road, depending on where they are coming from. View the full detour map here.

While Lakemont Boulevard is not in Newcastle, many residents use it as an alternate way into the city, especially those coming from Issaquah. The closure is necessary to complete a city of Bellevue roadway improvement project.

The other traffic impact is connected to construction of the new Renton School District middle school at the corner of Newcastle Way and 116th Avenue Southeast.

Expect delays as street improvements take place in conjunction with the school’s construction. Lane closures aren’t expected, but lanes will be shifted and flaggers will be on site to direct traffic.

Work is expected to begin on Newcastle Way as early as the third week of June and expected to be completed by Aug. 31.
