Glossary...

So often, the terms used to describe highways, such as “freeway” and “expressway” are misunderstood. Here are the terms used to describe roads (both 4-lane and 2-lane) on this web site, from the highest to the lowest standard of construction.

4-Lane Highways:

• Freeway - A highway with access only by interchange. There are no driveways or at-grade intersections.

• Expressway - A highway with restricted driveway access, but with a mix of grade-separated interchanges and at-grade intersections.

• Jersey Freeway - A highway with access at interchanges, side streets, and driveways, but with no median breaks or traffic lights.

• Arterial Highway - A multilane highway with a speed limit of at least 45 miles per hour.

• Boulevard - A multilane route through a developed area, providing direct access to commercial properties.

2-Lane Highways:

• Super 2-lane Freeway - A 2-lane highway with access only by interchange. There are no driveways or at-grade intersections.

• Super 2-lane Expressway - A 2-lane highway with restricted driveway access, but with a mix of grade-separated interchanges and at-grade intersections.

• Improved 2-lane Highway - A 2-lane highway that has no access control, but has been relocated or rebuilt to high standards. These highways may have paved shoulders, straightened curves, wider lanes, or higher speed limits.

• 2-lane Highway - Any other 2-lane highway outside of a town.

• City Street - A 2-lane road inside a town or city, with a speed limit below 35 miles per hour.
