Haggetts Pond is the reservoir for the town of Andover, Massachusetts, United States. It is located in the western part of the town and also lends its name to a road. The Merrimack River is connected to the pond to add volume to the reservoir. It is bordered by Route 133 on the south. Not far to the northwest is Interstate 495; to the northeast is Interstate 93. Permissible activities include walking, hiking, jogging biking and fishing. Only registered rowboats are allowed on the reservoir and fishing must be done from either the shoreline or a rowboat (no hip waders). Canoeing or kayaking, windsurfing, sailing, ice skating and ice fishing are prohibited. Swimming, bathing, wading and pets in the water are also prohibited. Hiking trails, some converted out of a former railway (the Lowell and Lawrence Railroad), encircle the pond. The Pond also gives its name to a road (Haggetts Pond Road) that starts to the west of the pond itself. Haggetts Pond Road transverses Route 133, but the vast majority of its length is on the side north of the pond. (Of the 245 houses on Haggetts Pond Road, 240 of them are on the north side.)

The Ballardvale District in Andover, Massachusetts, encompasses the historic mill village of Ballardvale in the northwestern part of the town. It is centered on the crossing the Shawsheen River by Andover Street, and includes buildings on High Street, Center Street, and other adjacent roads on both sides of the river. The district was listed on the National Register of Historic Places in 1982.Ballardvale was the first planned mill community in Andover. John and William Marland were the principal investors in the Ballardvale Manufacturing Company, under whose auspices the area was developed. It was named for Timothy Ballard, who had previously operated a sawmill and gristmill at the mill location set up by the Marlands. For about 100 years between 1835 and 1935 there was a remarkably self-contained community here: in addition to the mills, it included shops, churches, a school, and a railroad station.The Marlands owned about 50 acres (20 ha) of land which was developed for the community. Much of the housing was relatively modest cottages on small lots, with popular styling details of the time. Many of them were built by locally notable builder Jacob Chickering. One typical house is at 36-40 Center Street: it is a four-family 2+1⁄2-story wood-frame house with minimal Italianate styling.There are four major mill structures that survive. The oldest building, dating to 1836, is a four-story brick construction with granite trim. A wooden mill building (1844) stands adjacent, and there are additional buildings in the complex that were built later in the 19th century. One other notable structure is a c. 1872 wrought iron truss bridge that crosses the river below the mill complex.

Lowell Junction is a railroad junction located in Andover, Massachusetts, about one mile south of the village of Ballardvale. The junction was created by the Boston and Maine Railroad in 1874, when they ran a branch line off their main line to connect with the city of Lowell in order to compete with its rival the Boston and Lowell Railroad. The branch line was built under the name of the Lowell and Andover Railroad and gave the B&M a direct link between Lowell and Boston which it did not have before because of a 30-year monopoly that the Boston & Lowell was granted when it received its charter in 1830. By 1865, the monopoly was gone and the B&M was free to build a line to Lowell. The rail junction is still in use as of November 2016 by Pan Am Railways as part of its Freight Main Line between Maine and upstate New York, but the connection between the former Lowell Branch and the main line heading south to Boston is not in service, as the freight service between Lowell and Boston is run down the old Boston & Lowell main line. Before the junction was put in, the area was very rural and part of Ballardvale Village. After the junction went in, Lowell Jct has built up with industrial parks, office buildings and small neighborhoods. Today, Lowell Junction sees up to 10 Pan Am Railways freights daily. New Hampshire Northcoast Corporation also runs two nightly freights under Pan Am Railways symbol, DOBO/BODO
