About The Project

In Bayonne NJ, route 440 runs directly through the city, dividing the community. There are residential zones and a train station on the west of the highway, and there are commercial zones on the east side. Over the years, there have been multiple deaths of pedestrians attempting to cross this highway. Our goal is to improve pedestrian safety and connect the residents and transportation hub with the commercial zone by designing a pedestrian crossing over route 440.

The image explains the layout of the site the team is attempting to fix. On the east, a train station and a neighborhood lies, and on the west, there is a commercial zone. The east and west are divided by highway route 440.

Spring Semester Summary

In Bayonne NJ, route 440 runs directly through the city, dividing the community. There are
residential zones and a train station on the west of the highway, and there are commercial zones on the east side. Over the years, there have been multiple deaths of pedestrians attempting to cross this highway. The team’s goal was to improve pedestrian safety and connect the residents and transportation hub with the commercial zone by designing a pedestrian bridge over route 440. The design consisted of a 130-foot single-span truss bridge structure using HSS steel members welded together. The members were optimized so that the most critical sections were above 84% maximum capacity when given the largest required loading. The five different types of members used were 10x6x.25, 10x6x.188, 8x4x.188, 6x3x.25, and 2×1.5x.125. To adhere to AASHTO standards, the bridge stood with a bottom deck height of 23 feet above the highway, clearing all vertical height requirements. The maximum deflection of the bridge after loading was 1.56 inches, which is less than the 4.4-inch maximum allowable deflection. The bridge rising and landing structure also conformed to ADA requirements, allowing the bridge to be safe and accessible to anyone. Engineering design costs for this project were estimated at $17,300, and the construction cost for the bridge was $1,040,000.
