As we celebrate St. Patrick’s Day, a time to honor Irish heritage and contributions, it’s important to remember the incredible impact Irish immigrants had on shaping New Jersey’s history—especially through their labor on the Delaware & Raritan (D&R) Canal.

In the 1830s, thousands of Irish laborers took on the grueling task of digging the 44-mile-long canal by hand. With only picks, shovels, and sheer determination, they carved out a waterway that would become a crucial transportation route for coal, goods, and passengers. Despite facing harsh working conditions, low wages, and discrimination, their hard work helped fuel the region’s economy and connect communities.

Today, the D&R Canal State Park stands as a lasting tribute to their resilience and contributions. As we wear green and celebrate St. Patrick’s Day, let’s also take a moment to recognize the Irish immigrants who built the foundations of our infrastructure—their sweat, strength, and sacrifice still shaping New Jersey today.
