As of now, the Maungatapu Bridge is under the process of construction. The Maungatapu underpass was reopened on June 22, 2018. In July 2018, the New Zealand Transport Agency set up a trial run that lasted for ten days. This trial closed off the straight through option of the bridge and allowed for people to only use the roundabout. In doing this, the hopes of those in charge of the project and the trial was to see if the new design was efficient and safe. It gave the planner a chance to gather information regarding the traffic flow and travel times of the new design. The construction consists of four stages, three of them already completed, while the remaining is still in works. The first stage dealt with the addition of street lights, the second stage was improvements to the intersections, and the third had to do with gathering data that would best help those in charge of the project in coming up with the best new design.
