Construction at Highway 525 and Highway 20 intersections will now extend into the weekend, the state Department of Transportation announced.

The intersections are being upgraded to meet American Disabilities Act standards as part of a $15.4 million road project that began earlier this month. Though the work was planned to cease over the weekend, department officials said those plans were altered at the request of the contractor, Granite Construction.

“I’m pretty sure it has to do with the weather and staying on schedule,” said Andrea Petrich, a spokeswoman for the agency.

The work will not be during the day, however; it’s scheduled to take place at night between the hours of 9 p.m. to 5 a.m.

The bulk of the project, repaving of about 30 miles of highway from Clinton to Coupeville, is also planned to take place during the week to limit the impact on summertime events and festivities. Petrich said the state hopes to keep to that promise, but there could be exceptions. Any changes will be announced.
