The Town of Billerica is located 20 miles northwest of Boston and borders Lowell to the south. Incorporated in 1655, the town remained predominately agricultural until the mid-nineteenth century when a major mill complex was sited on the Concord River in North Billerica. Currently Billerica has close to 40,000 residents. The town is within minutes of Routes 3 and 495. The town has bus and train service provided by the Lowell Regional Transit Authority and the MBTA at North Billerica. The remnants of the historic Middlesex Canal, an outmoded mode of transport, traverse the town north to south. Two rivers pass through town. The Concord River is a major regional water feature while the Shawsheen River rambles through the southerly part of town.
