Boston Post Road: Indian trail to Turnpike to U.S. Route 1

Boston Post Rd: Boston Post Road existed by 1673 on the route of a former Indian trail. In 1661 when John Richbell purchased Mamaroneck, there was an Indian Trail referred to as the Secarah (in English, the Shore Path). This trail was referred to by colonists at that time as the Westchester Path. It didn’t cross the Mamaroneck River where Post Road does now. It wound up what is Mamaroneck Ave, down what is Prospect Avenue and then forded the river at the ledge of rocks where the sweet water falls into the salt.

By 1696 a bridge was built across the river at or about that point and at some point after that, Tompkins Avenue was the Westchester Path, which continued until it reconnected with the Boston Post Road, but the original Westchester path would have crossed about there (as opposed to the current crossing of the Post Road Bridge) even before there was a bridge.

This path was an Indian Trail, not much more than a foot path since the Indians in this area didn’t seem to use horses. By 1673 it would have been widened to at least accommodate a horse because it was the designated route for the postal rider. Governor Lovelace travelled to Hartford on this route later in 1673.

The road appears on a 1797 map as the Country Road and on an 1820 map as Turnpike and Old Boston Road. In 1800 the road had been expanded from two lanes to four and took its current route. Now called the Westchester Turnpike, it bypassed the Old Post Road and crossed the Mamaroneck on a new bridge continuing in Rye and bypassing Tompkins Ave.

Where the info came from: View vintage maps

We compiled this information mainly from vintage maps and atlases from the Mamaroneck and Westchester historical society collections. For more recent decades, we consulted Westchester County atlases in the Mamaroneck and White Plains libraries. .

To pinpoint the timing of some streets we also checked years homes were built there.

You can view many of the vintage maps on the Mamaroneck Historical Society website's maps pages:
