The multi-million pound, 100 tonne Brayford level crossing footbridge was finally pieced together overnight with the arrival of the central walkway and steps.
The prehistoric-looking structure was craned into place after being transported from a workshop in Newark.
Work will continue on the new bridge until, Tuesday, May 14 and the level crossing will reopen on Wednesday, May 15.
The project hit a number of issues due to the condition of the ground near on the waterside and has suffered a number of delays.
Closures have also led to disruption for pedestrians travelling North/South of the Brayford, as well as university staff and students.
