The traffic systems section of the Highway Department manages the:
City's regulatory and street signage
Steel beam safety guardrails
Installation of new and annual refreshing of pavement markings
Work zone safety program for department operations
In 2003, the department began the multi-year systematic replacement of the older green street signs with new high-visibility blue street signs that comply with the current federal highway administration standards.
The new signs have a higher level of reflectivity and larger lettering to enhance readability in periods of minimal luminescence.
The Traffic Systems Group manages the repainting of:
Yellow center line
White edge line
In addition, the department installs and/or replaces hundreds of regulatory signs and advisory signs either by direction of the Board of Selectmen or as required through routine maintenance practices.
