Guided buses are set to return to two-way running after the installation of a new safety measure.
The Busway between Cambridge railway station and the Cambridge Biomedical Campus is due to fully reopen on Saturday.
Work began on February 12 to install fencing along the route over the past six weeks to improve pedestrian and cyclist safety.
Three people have died in separate busway incidents between 2015 and 2021, with a fourth suffering severe injuries.
The last section of work has seen the busway closed from Hills Road bridge to Addenbrooke's spur and the maintenance track closed from Hills Road bridge to Long Road bridge.
However, the maintenance track from Hills Road bridge to Long Road bridge - the path that runs alongside the busway for cycling, walking, and running - won’t open until April 6.
Cambridgeshire County Council confirmed the work was due to finish on March 29, but said that heavy rain caused issues with holes drilled for fence posts.
Pumping equipment was brought in to pump excess water and an additional week will be required to complete the work, including installation of the final sections of gates and panels.
A Cambridgeshire County Council spokesperson added: “Our contractors have been working seven days a week to get this work completed as quickly as possible and involved removing the existing temporary fence, taking out the kerbs and installing the new fence.
“To reduce inconvenience to bus passengers, cyclists and pedestrians and keep the Guided Busway and the maintenance track open wherever possible, the work took place in sections.
They added: “This new safety measure means we can return the busway back to full use and people can continue cycling, walking, running, and using the maintenance track.
“This is the best way forward and part of our ambition to make travel across the county safer and more environmentally sustainable.”
