The total project investment is estimated at US$1.17 billion.

The purpose of the project is to implement a transportation solution that improves safety, access and mobility. The need for the project results from the following issues: increased transportation demand, limited transportation capacity, safety concerns; and transportation infrastructure deficiencies.
