In addition to the amazing photo contest image, ENR has a new touch on the magazine’s cover this week. Our logo has been refined and our tagline updated to keep current with our digital transformation. ENR now delivers news to subscribers via electronic news alerts 365 days a year—not just once week —and on our website 24/7. Our print magazine, published 36 times a year, is “the construction resource” of the industry for analysis, data and commentary in addition to news.
