The Route 624 (Happy Creek Road) project provides safety improvements from the Town of Front Royal Eastern Corporate limits to Route 645 (Manassas Run Road). Route 624 is a two-lane road with 10-foot wide travel lanes. Work includes widening the lanes to 11 feet, reducing fixed object hazards, increasing intersection capacity and improving drainage.

On a portion of Route 624 is a wooded area with a curve, which currently limits drivers’ sight views. This area will be cleared and the curve reduced to improve visibility.

In the middle of the project is an at-grade crossing for the Norfolk Southern Railroad. Trains at this crossing serve the Virginia Inland port which is located north of Front Royal. Route 624 has a curve at the crossing, which will be reduced with a slight roadway realignment. Reflective signs and chevrons will be posted to help drivers see the road particularly during night and low light conditions.

Turn lanes will be constructed on Route 624 at Route 647 (Dismal Hollow Road). 

A portion of Route 624 will be closed to through traffic between June 19 and August 6, 2021. Detour information is in the Traffic Alerts section on the right side of this page. Prior to the closure, motorists may see work crews erecting signs and preparing the work zone area. Drivers are asked to use extreme caution and be aware of flagging operations and be alert for people and vehicles working in the area.

In 2016 Route 624 had an average daily traffic count of 4100 vehicles per day. By the design year of 2043 the estimated average daily traffic volume is 5800 vehicles per day. The total estimated cost for this project is $5.8 million, including $1.3 million for preliminary engineering, $900,000 for right of way and $3.6 million for construction.


This project will improve safety on Route 624 by reducing fixed object hazards, increasing intersection capacity and improving drainage.
