Check out this Behind the Scenes look from the I-10 Broadway Curve Improvement Project to learn more about the soffit fill that is used to support the construction of new bridges. This soil is placed during construction of the new bridge decks and then removed once the bridge deck is complete. For more information on the Arizona Department of Transportation's I-10 Broadway Curve Improvement project, visit the project website at i10broadwaycurve.com or on "The Curve" mobile app.
