[22] Before Montague Township was granted its own post office in the 1980s, residents had all of their mail delivered through the 12771 ZIP code for Port Jervis, New York, leading to situations where residents had New Jersey driver's licenses with a New York State mailing address.

U.S. Route 206 passes through in the western part and crosses the Delaware River at the Milford-Montague Toll Bridge.

Route 23 passes through the eastern part and serves as the entrance road to High Point State Park and ends at the New York border just south of Interstate 84.

County Route 521 enters Montague concurrent with US 206, separates from US 206 just south of the Milford-Montague Toll Bridge, then heads northeast through the northwest portion of the township before ending at the New York state boundary.

The closest limited access road is Interstate 84 and is immediately over the state line in Deerpark, New York.

In the northernmost section of the township along Route 23, there are several gasoline stations, most likely because gas had historically been significantly less expensive in New Jersey than in Matamoras, Pennsylvania or Port Jervis, New York.
