Public transportation
NJ Transit Bus Operations routes 114 and 117 provide service to the Port Authority Bus Terminal in Midtown Manhattan in New York City while routes 65 and 66 travel to Downtown Newark, all making local stops at points in proximate communities.[99] An early use of bus rapid transit in New Jersey, a BBS (bus bypass shoulder, originally called a BOS or bus on shoulder lane) has been in operation for many years. Unlike most municipalities along Route 22, zoning in Mountainside does not allow for much commercial development adjacent to the freeway.[100] For a one-mile stretch in the town, the eastbound shoulder on the arterial road can be used for peak hour buses.[101] In 2012, the New Jersey Department of Transportation (NJDOT) regulated the BBS as an exclusive bus lane from 6 to 7:30am.[102] In 2009, NJDOT funded construction of two bus turnouts along the road in nearby Union.[103]
Newark Liberty International Airport is approximately 11 miles (18 km) east of Mountainside.
NJ Transit rail service is accessible via Summit station, and it has frequent direct service to New York Penn Station. The station is located around 2 miles (3.2 km) from the center of Mountainside, and Westfield station, which is about 4 miles (6.4 km) away, is also nearby.[104]
