LINCOLN, Neb. (AP) — Road planners are considering “super two” highways as ways to stretch Nebraska’s highway dollars.

The two-lane highways have wider shoulders and an extra passing lane every five miles or so.

Nebraska Roads Department engineers say the design could increase traffic flow at less than half the price of a new four-lane highway.

The department hasn’t yet announced where super twos might be used. State officials have encouraged communities to consider super twos as alternatives for lower-priority projects.
