Traffic Signal Installations / Modifications

Project Description
New signal construction continues in 2021, including adjustments to the timing of signals to better handle traffic volume fluctuations as impacts related to Covid-19 abate.   Signal timings were initially adjusted to shorter cycle lengths to reduce delay for the traveling public as volumes dropped significantly during the 2020 timeframe.  As traffic volumes increase, signal timings were adjusted back to normal cycle lengths to better handle prevailing volumes.  All timing adjustments were made in cooperation with the adjacent signals owned and maintained by CDOT and City of Littleton.  Flashing Yellow Arrow (FYA) implementations continue to be rolled out where conditions warrant these operations. Anticipated projects in 2021 include:

  • County Line Rd & Quebec St Intersection Improvements (Centennial Project to add SBR turn lane) – anticipated early summer 2021 completion
