Columbia Pike Four Mile Run Bridge Pedestrian Enhancements

Construction Update – April 2021

The first phase of work is scheduled to start the week of April 19, weather permitting. Initial activities will include mobilization of equipment, installation of traffic control and tree protection, and then beginning to remove the existing northern sidewalk.

During the first phase, the right westbound lane on the bridge will be closed during weekdays from 9 am to 4 pm, which will reduce the number of westbound travel lanes from two lanes to one.

What to expect during construction:

Work hours will generally be 7 am to 4 pm, Monday through Friday.
- Work on weekends and holidays is subject to prior approval by the County.
Lane closures will occur weekdays between 9 am and 4 pm.
The bridge’s northern sidewalk will be closed – People walking, biking and rolling will be detoured to the southern sidewalk using the crosswalks at Four Mile Run Drive and South Dinwiddie/Columbus Street.
During work hours, loud noise is anticipated as the contractor uses equipment to break up existing concrete and other items.

Status

Construction

On Jan. 23, 2021, the County Board voted unanimously to approve the award of an approximately $1 million contract, including contingency, to widen the Columbia Pike Bridge over Four Mile Run’s sidewalk and perform maintenance and minor repairs to the bridge deck.

Implementation of the improvements is expected to start in April 2021, with completion in fall 2021.

About the Project

Project Goals

Project Background

Throughout the engagement process for the Columbia Pike west end project, County staff received feedback about the pedestrian experience on the bridge’s north sidewalk. Concerns centered around the sidewalk feeling too narrow and too poorly lit at night to feel comfortable or safe.

Following community meetings in spring 2019, staff began exploring options for improving the northern sidewalk and determined there is room for sidewalk expansion within the existing bridge width. This expansion would provide a 10-foot-wide shared sidewalk space and Carlyle-style lighting on the bridge’s north side.

About the Process

County staff shared information about the pedestrian enhancements for the Columbia Pike Four Mile Run Bridge at several community meetings and events, including:
