MONMOUTH — Highway 99W through the Monmouth remains open during construction — but expect delays and detours.

The Oregon Department of Transportation released the following update on Aug. 29:

• The center turn lane of OR 99W is now open.

Work Hours

Construction work will continue throughout the day and late evenings with single-lane closures nightly, from 7 p.m. to 6 a.m., Sunday nights through Friday mornings.

The project started in September 2018, and is expected to be completed by December.

This project will:

• Replace highway pavement and underlying structure, which is in poor condition.

• Rebuild pedestrian access ramps and crosswalks to meet current ADA standards.

• Add bike lanes, a continuous two-way center turn lane, and landscaping.

• Add new railing and a waterproof membrane to the Middle Fork Ash Swale Bridge.
