Website Town of Coeymans

Coeymans is a town in Albany County, New York, United States. The population was 7,418 at the 2010 census. The town is named after an early settler, who was the patent-holder for the area. The town is in the southeastern part of the county, south of Albany.

The Powell & Minnock Brick Yard, just north of the Hamlet on Rt. 144, was used as the assembly site for a new swing span for the 145th Street Bridge in 2006. The site was chosen because of a lack of space closer to the city.


Barent Pieteres Koijemans first arrived in 1639 from Holland. He became an apprentice at a mill owned by the Van Rensselaers.

Coeymans was formed from part of the town of Watervliet in 1791. In 1815, part of the town was used to make the new town of Westerlo.

The Fletcher Blaisdell Farm Complex, Coeymans School, Ariaanje Coeymans House, Coeymans-Bronck Stone House, Mull House and Cemetery, Tobias Ten Eyck House and Cemeteries, and Cornelius and Agnietje Van Derzee House are listed on the National Register of Historic Places.


According to the United States Census Bureau, the town has a total area of 53.1 square miles (137.5 km²), of which, 50.2 square miles (129.9 km²) of it is land and 2.9 square miles (7.6 km²) of it (5.50%) is water.

The south town line is the border of Greene County, and the east town line, marked by the Hudson River, is the border of Rensselaer County.

Interstate 87 and U.S. Route 9W pass through the town.

The Economy of Coeymans is driven largely by Lafarge Cement Plant, and Port of Coeymans which was developed over the former site of the Powell and Minnock brick plant on the shore of the Hudson River. The Lafarge Cement Plant generates approximately 1.8 million tons of cement per year, which is distributed throughout North America. The relatively new and developing Port of Coeymans focuses on a recycling hub for the Albany area, as well as offshore wind.
