April 2022

As part of the on-going design work for Mill Street, the City will be conducting geotechnical explorations to support the design of a new roadway pavement surface.  Workers will be in the roadway on April 21st, 25th, and 26th to collect surface and subsurface information necessary to develop a new pavement.  During these days, only one lane will be open to traffic in alternating directions for short segments on Mill Street between S. A Street and W Centennial Boulevard.  Flaggers will be onsite to direct traffic.  Drivers should expect minor delays.

The Mill Street Reconstruction Project is moving forward. The design phase is now beginning, starting with survey work scheduled to begin on February 28, 2022. For more information, read the February letter to residents.

Project Overview

Mill Street serves as a collector for residences and some commercial use, and provides access to Centennial Boulevard and Main Street, two key Springfield arterial streets. Over time, the street has reached a state of deterioration beyond the feasibility of maintenance treatments.

In addition to crumbling pavement, Mill Street currently presents challenges to pedestrians and bicyclists. Cyclists currently ride in the roadway and weave in and out of parked cars along the street. Between 2008-2015, nine bicyclist-involved crashes were reported along the project length. All except for one were angle, sideswipe, or turning movements, which are the types of crashes that could be expected to occur without good visibility of people biking and without infrastructure that encourages more predictable riding behavior, such as a bike lane.

Mill Street is also heavily accessed by pedestrians walking to Centennial Boulevard or Pioneer Parkway to use the bus. Reconstructing Mill Street provides an opportunity to enhance the safety and accessibility of curb ramps and pedestrian crossings to allow for continued, safe access of commonly used pedestrian routes to get to and from the nearby bus lines.

Construction is planned for 2024.

Project Goals

The reconstruction of Mill Street from S ‘A’ Street to Centennial Boulevard aims to achieve the following:

  • Create a new transportation asset that will serve our community for many years by fully reconstructing a major collector in complete disrepair.
  • Improve accessibility for pedestrians and bicyclists by addressing pedestrian crossings, bring curb ramps up to meet ADA standards, and fill in a missing gap in the Springfield bicycle network.
  • Improve street lighting to make the area more walkable at night and increase the safety of all users.
  • Rehabilitate wastewater lines. This is necessary to enable the City to maintain compliance with federal and state requirements to eliminate wastewater overflows.
  • Improve stormwater facilities. Stormwater Management is an important part of the community’s effort to improve water quality, protect fish habitat, and protect properties and infrastructure from flooding. Stormwater flows to storm drains, gutters, ditches, swales, or a system of pipes, eventually ending up in the McKenzie or Willamette rivers. Unlike wastewater from indoor plumbing, stormwater is not treated before being emptied into our waterways.
