Smart Zone Tools Will Provide Travel Conditions for 1-91 Bridge Replacement

from-west-river-final-bridge-largeThe PCL+FIGG Team that is working under contract to the Vermont Agency of Transportation to reconstruct I-91 bridges in Brattleboro is using a full array of “Smart Zone” tools, including Portable Changeable Message Signs (PCMS), Wavetronics radar traffic sensors, and video cameras that will broadcast live data to a public website devoted to the project. The site’s traffic sensors will continuously monitor traffic volumes in the work zone. This information will be used to automatically post messages on project signs regarding potential delays and expected travel times.
The project website ( includes live video 24/7 of traffic conditions in the construction zone from several locations and also depicts the messages posted on the project’s portable signs.
VTrans and the PCL+FIGG Team has access to the administrative side of the website and is able to monitor the work zone for traffic congestion and incidents requiring emergency responses, including disabled vehicles and crashes. When situations such as these occur and public notification is warranted, the PCL+FIGG Team will be able to change messages on the project’s PCMS signs remotely to alert drivers and website viewers of changes in travel conditions.
If you would like more information about the bridge replacement project, or would like to receive e-mail notices of future travel restrictions associated with this project, please contact Cindy Cook at or (802) 223-1330.
