Traffic studies have been conducted for the Boxwood Connector Project in 2010, 2013 and 2016. These studies reviewed traffic volumes and patterns in the project area in detail. The studies conclude that traffic operations could be improved with the Boxwood Connector. The studies also indicate that improvements on Northfield Road can be phased, and that the ultimate road widening between Bowen Road and Boxwood Road can be completed several years after the Boxwood Connector project is constructed, or as adjacent properties redevelop.
The Boxwood Connector was identified as a major road improvement project in the 2014 Nanaimo Transportation Master Plan.

The project site was the former location of mining waste disposal and construction fill material dumping. As a result of this historical land use, soil and groundwater contamination is present within the site. Significant environmental studies and investigations have been conducted on the property to determine the types and levels of contamination. With this information a detailed environmental remediation plan that meets provincial regulations was prepared and used to apply for the necessary approvals to proceed with the project.
The proposed habitat compensation for the Boxwood Connector project includes the construction of a naturalized public area including riparian planting, and will serve as a detention pond during storm events. The project has been carefully designed to improve the function of many environmentally sensitive features that have been previously disturbed from historic impacts.

Significant geotechnical investigations have been conducted on the project site. Beneath the top surface is an assortment of materials and conditions including layers of historic mining waste and construction fills, layers of organic peat and soft soils, and layers of compact to dense native soils.
The site will undergo extensive geotechnical and environmental improvements during Phase 1 in 2019, including the placement of pre-load material that will be left for 2 years to help compact the soil for the future roadway improvements.
After the soils under the future roadways have stopped settling, the pre-load material will be removed from the site and final ground improvement can be finished. This will involve specialized construction equipment that compresses the soil through a method called 'rapid impact compaction'.
