The April 15 print issue of ENR Mountain States will include a list of some of the largest new projects that broke ground in our seven-state region last year. We have been seeking projects that started actual construction between Jan. 1 and Dec. 31, 2023 and welcome your submissions.

Our sources include information from Dodge Data & Analytics, surveys from individual firms and other industry reports. The projects can be located in any of the Mountain states—Utah, Idaho, Montana, Colorado, Wyoming and the Dakotas—and represent any type of construction, from pipelines, heavy-highway and infrastructure work to new building projects and renovations. 

If you have a big project that broke ground last year within the region and think it should be included on our list, please e-mail me the details, including the project name, location, dollar amount, date started, contractor, owner, design firm and scheduled completion, at or call me at 303-999-6414.
