I-40 and Meteor City

The Interstate 40 bridge at Meteor City Road that has been in the process of being replaced since mid-July is being built using a new technique, according to the Arizona Department of Transportation.

The technique, called a geosynthetic reinforced soil-integrated bridge system, creates abutments by alternating layers of granular fill reinforced with synthetic material.

The approach makes it possible for the bridge replacement to take less time than usual, and will also create lower maintenance costs, according to an ADOT press release.

This will also be Arizona's first project that will see the construction of a new bridge deck using a polyester polymer concrete . This material will speed up curing time and also reduce maintenance costs.

In addition to replacing the bridge, crews will reconstruct the roadway approach to the bridge.

The current detour that takes I-40 traffic onto the Meteor City Road off- and on-ramps to move through the work zone will last through mid-August.
