Opinion | We fixed I-95 in 12 days. Here are our lessons for U.S. infrastructure.

Fourth, work together. At every step of the I-95 project, local, state and federal officials coordinated closely with each other, and the collaborative approach extended to our private contractors and organized labor. Some politicians may criticize unions, but here in Pennsylvania, we saw a proud and diverse group of more than 200 members of the Philadelphia Building Trades work around-the-clock, through heat and rain and Father’s Day weekend, to get the job done safely and with tremendous skill.

The eyes of the nation were on the rebuilding of I-95. I hope Americans can use some of its lessons in taking advantage of the opportunity to safely, quickly and smartly strengthen our nation’s infrastructure.
