Work to implement a pilot project, that calls for the installation of separated bike lanes on Butler Avenue, will begin on Monday. City officials say the project limits are Butler Avenue from Milton to Sawmill Road. Traffic control devices and lane restrictions will be implemented throughout the week and motorists are encouraged to seek an alternate route or be prepared for delays as they travel through the project area. The work is the beginning stages for a pilot project that will implement a separated bike lane for Butler Avenue. Construction on the project is expected to last until Friday.
