The estimated total cost for the four lane highway grading, construction of the bridges and interchanges, and the paving of a two-lane highway from U.S. 61/151 to U.S. 20 is $157 million. The Iowa Department of Transportation (DOT) has committed $115 million toward the construction of a preliminary two-lane highway. This phase is under construction and is scheduled to be completed and open for traffic in 2019.

The City of Dubuque has acquired $32.8 million in federal funds and will contribute an additional $6.1 million in local funds, along with $3.7 from Dubuque County to complete the preliminary two-lane highway. The remaining four-lane paving will be constructed when the Iowa DOT can budget for the additional funding.
