SALEM – During the last week of October, work will begin on a safety improvement project at the intersection of Route 460 and North Main Street in Montgomery County near the Blacksburg town limits. The project entails installing new flashing warning signs that will say “Watch for Entering Vehicles When Flashing” and detectors to activate the signs when vehicles are waiting to make a turn at the intersection.  

These signs are part of a safety improvement project and are intended to warn drivers approaching the intersection that turning vehicles are present on Route 460, North Main Street or Farmingdale Lane.

These flashing signs are more sophisticated than typical sign flashers that are lit constantly.  These new signs provide real-time information and will flash only when vehicles are waiting to make a turn at the intersection.  VDOT received federal safety funds for the project in July 2013.

Video detection zones will be created to activate the signs when vehicles are present.  The zones will be located in the intersection’s crossover, in the left-through lane on North Main Street and on Farmingdale Lane.  The cameras used to create the detection zones are similar to those used on traffic signals and do not capture recorded images.

This intersection is one of the highest crash locations in Montgomery County.  Analysis performed in February 2013 shows 41 intersection-related crashes in the seven year period from 2005 to 2011.  The most common collision type at this intersection is an angle crash between motorists turning left from eastbound Route 460 onto North Main Street.  The new signs should help reduce this type of crash by alerting drivers that vehicles are waiting to turn at the intersection.

VDOT has completed several other safety measures at this intersection including upgrading signage, installing new pavement markings and cutting back trees.

The new signs and detection system will cost $137,479.  Installation is anticipated to be completed sometime in November.  Drivers can expect periodic lane closures at the intersection on weekdays outside of peak travel times for the installation.
