 When Palmer's major roadway system first started to develop in the 18th century, it was dictated largely by the trails leading from Easton to outlying communities.William Penn Highway, the first road built in Palmer in around 1755, led from Easton to Bethlehem.Likewise, Freemansburg Avenue leads from Easton to Freemansburg; Old Nazareth Road leads from Easton to Nazareth; Tatamy Road leads from Easton to Tatamy; and Hecktown Road and the Newburg Pike leads from Seipsville to the Hecktown and Newburg communities.
