Which street runs alongside the port area of Monmouth?

Port-au Peck Avenue is the correct answer as it is directly associated with the port area of Monmouth. The name itself suggests a connection to the port, referring to its geographic location. This street runs alongside the waterfront, offering access to the port and facilitating various shipping and transportation activities typically found in such areas. Its proximity to the water makes it a vital roadway for businesses and services that operate near the maritime facilities.

Other streets listed, while they may be located in Monmouth, do not have the same direct connection to the port area. For instance, Branch Port Avenue and Broadway do not pertain specifically to the waterfront's commercial activities, and Joline Avenue, though present in the vicinity, does not serve as the major thoroughfare within the port area. Understanding the relationship between streets and their surrounding areas helps in navigating local geography effectively.
