Due to F35s coming to Eielson, there will be highway construction around MP 337 on the Richardson where the 'new' south gate is located. This project is intended to make this area safer for the volume of freight traffic that will be associated with the F-35 going onto Eielson.

This is Need ID 30449, Richardson Highway MP 337 Eielson AFB Intersection
Improvements.

Intersection improvements at the southern access of the Eielson
Air force Base at MP 337 of the Richardson Highway to
accommodate additional freight volumes in support of the
addition of two F-35A aircraft squadrons.
