The Gull Wing bridge will cross Lake Lothing and link Waveney Drive to Denmark Road and Peto Way. It is expected to open in the summer of 2023.
The £126.75m third crossing is more than 100 years in the making and has been delivered by Suffolk County Council and built by Farrans Construction.
The bridge aims to reduce traffic congestion in the town, helping to regenerate the area and attract new investment to the local economy.
Gull Wing's development is being documented by CHPV, a Lowestoft-based media company.
The team, which primarily works in offshore energy, installed two time-lapse cameras to capture the build.
The construction work on the Gull Wing will eventually see the installation of two new roundabouts, ground improvements, eight bridge spans as well as the construction and refit of a control tower, alongside other works.
