Chatham has only one traffic light; right turn on red is allowed at that intersection. It has 49 stop signs, 11 yield signs, and one traffic circle. In addition, there are 121 signs regulating parking.

Previous to the NYSDOT renovations, cars driving in the traffic circle on Main Street yielded to cars entering the circle, which is an unusual traffic pattern. This pattern was changed to be in compliance with NY state traffic laws in 2008. NYSDOT supplied funding to rebuild Main Street including installing a new water main, drainage structures, granite curbing and concrete sidewalk. Main Street was closed to vehicular traffic during this period. After Main Street's existing pavement was excavated, the road was filled with crushed stone, providing pedestrian access to shops along the street. Various side streets were repaved with asphalt and new curbing and sidewalk was installed as well. A new retaining wall with H-pile was built on Hudson Avenue. This work was carried out in 2008 and 2009. The prime contractor was A. Colarusso & Son Inc., based in Hudson, New York. During construction, NYS Senator Stephen M. Saland showed up briefly to witness progress.

The village was a hub of the New York Central, Boston and Albany, and Rutland railroads, with three wyes and one roundhouse.
