In November 2019, ZCC was awarded a $35 million contract with the North Carolina Department of Transportation to enhance the Interstate 40 and Airport Boulevard Interchange in Morrisville. The Zachry crew is expected to begin work in March 2020 and expect to finish in February 2024. The bulk of the work will be replacing the current single bridge with a Diverging Diamond Interchange (DDI) and adding auxiliary lanes to I-40 in both directions.
