The new bridge was designed to relieve the central parts of the city from car traffic, making a positive impact on the municipal climate goals for 2025 and 2030. The project also aided in the development of the public transportation system in the city.

The project was divided into five contracts, including construction of a new bridge, new alignment of the Ulleråker road, converting part of the existing Ulleråker road to a walk and bike path as well as rerouting of pipes and earthworks.

This contract (E01) included pipe rerouting, preparatory work in the existing street structure, as well as new stormwater facilities and reconstruction of stormwater and wastewater systems. The project is located in central Uppsala, along the Kungsängs esplanade and in its extension over the Fyrisån to connect to the Ulleråkers road.

Water environment

The project achieved 100% of points in this area.

Thorough handling of the risks of impact on the ground and surface water during construction included a control plan. The control plan covered, above following the permit, continuous checks of clouding in the river, amounts of water used, handling construction water with sampling and informing all project members in the importance of not impacting the ground and surface water. Strict handling of chemicals, tools and machinery made sure no negative impact on the river came from the project.

In addition to this, three facilities for sustainable storm water management were completed as part of the project. A macadam reservoir in one of the intersections, to delay storm water from the street and regulate flow. Curb wells and sand trap wells along the street were installed, letting water through, and catching larger particles. A new system for disaster protection was built as part of the project, replacing the old existing one. The new one is better designed to handle the amounts of water passing through it into the Fyris river, and includes a system for delaying flow, trapping oil and trapping sludge before releasing water into the river. The new system is also easier to maintain during operation.

The Tullgarnsbron Bridge project achieved a significant reduction in embodied carbon emissions, with approximately 50% reduction or ~80,000 kgCO2 equivalent saved compared to a traditional design. This reduction aligns with Uppsala Kommun's climate goals for 2025 and 2030, contributing to a more sustainable transportation system in the city.

CEEQUAL provided a good framework for sustainability, guidance in setting requirements for the design and construction and provided grounds for discussion and dialogue between the involved parties.
The assessment also led to a higher percentage of ECO-friendly products and fuels being used.
