Mount Vernon Highway and Long Island Drive Intersection Improvement

Long Island Drive and Mt. Vernon Highway Intersection Improvement Project

Current Status

Early project activities included underground utility verification, completion of traffic signal pole shop drawings and foundation design, tree removal, and installation of erosion-control measures. Signal pole foundation excavation and concrete placement were completed in mid-July.

Current construction activities include reconstruction of curb and gutter, sidewalks, and ADA ramps at the southeast and southwest corners of the intersection; removal of the existing median island; and demolition and reconstruction work along the Arlington Cemetery frontage, including driveway realignment and hydrant relocation.

Delivery of the signal poles and mast arms is currently expected in late October. Following delivery, installation of the power meter, traffic cabinet, and lighting is anticipated to begin in early November. Signal, electrical, and lighting work is expected to require approximately four to six weeks.

During November and December, pavement work, final striping, and signage installation will proceed concurrently with signal and electrical work, where feasible. The contractor will also prepare to shift traffic to the new traffic pattern to allow testing and activation of the new signal.

The project team is targeting substantial completion by the end of December 2026, with final project closeout anticipated in early January 2027. Lane closures and flaggers will be used as needed during construction, and motorists should expect periodic delays in the project area.

Project Description

The proposed project will improve the safety of the intersection, and operational performance, by adding a traffic signal at Mount Vernon Highway and Long Island Drive, including the driveway of Arlington Cemetery. Currently, the cemetery driveway is offset with Long Island Drive, which overlaps with left-turn movements on Mount Vernon Highway. Long Island Drive sees heavy queuing and long delays at the stop sign at Mount Vernon Highway. Additionally, when vehicles are queued in both lanes of the approach, sight distance for drivers is obstructed.

This project will install a new traffic signal, widen the roadway, and realign the driveway of Arlington Cemetery. There will also be new sidewalks, and upgraded striping and signage.

Public Engagement
