Construction Update on the

Century Boulevard Extension Project

Thank you for your patience as construction continues.

Here's what to expect in the coming weeks:

Utility Trenching

Trench construction is expected to be finished Friday, November 13.
Utilities will start moving their lines from poles to the trench.

What to Expect:

Expect flaggers and intermittent lane closures.
Trenches will be covered daily at the end of each workday.

Rock Creek Area – Bridge & Wall Construction

Groundwork continues for the mechanically stabilized earth (MSE) wall on both sides of Rock Creek with fill dirt being placed.
Pile installation will begin for bridge supports for bridge columns.

What to Expect:

Piling driving for the bridge supports is expected to begin Thursday, November 19.
Pile driving will occur Monday thru Friday, during the day.
No pile driving will occur on Thanksgiving (November 26).
No pile driving will occur on weekends.
To limit noise impacts, the piles will first be vibrated down, until the soil resistance becomes too great and it is necessary to use a pile driving hammer.
There will be intermittent breaks to weld sections of pile together, conduct tests, and move between pile locations.
Pile driving is expected to take a two-three months. Check webpage for updates.

Lighting Installation – NE Oelrich & NE Dogwood

Contractors are installing new light poles at the intersections of Oelrich aand Dogwood streets the week of November 16.
Once complete, the City of Hillsboro will be cleared to install Rectangular Rapid Flashing Beacons (RRFBs) to help pedestrians and bicyclists more safely cross the intersections.

Mobility Impacts

Temporary pedestrian access routes will be installed to ensure people have a safe route to walk along Century Boulevard.

Lanes will be shifted and temporary lane closures can be expected on Century Boulevard as the contractor starts digging the utility trench. One lane will remain open in each direction with temporary delays.

The bike lane of the eastbound lanes on Main Street will be closed while the contractor moves equipment into the area but will remain open otherwise.

No road closures are planned in the coming months.
