Freeway Gaps

Freeway gaps are sections of signed U.S. Interstate routes that do not meet the standards for controlled-access highways. The non-exhaustive survey presented here depicts three types of these gaps:

• At-grade intersections, which may include traffic signals and pedestrian crossings.
• Narrow stretches of road, which may be single lane, lack shoulders, or be undivided.
• Movable bridges (e.g., drawbridges) which may impede the free flow of traffic.

This survey is based on the Wikipedia entry List of gaps in Interstate Highways. The imagery in this survey is sourced from Google Street View, in accordance with their usage guidelines for non-commercial / non-academic projects. Some symbols used in this survey are adapted from the Manual on Uniform Traffic Control Devices, issued by the United States Federal Highway Administration. The map of U.S. Interstate highways is sourced from Wikimedia Commons, and is based on information from the National Atlas of the United States, issued by the U.S. Department of the Interior. The text is set in the font family Overpass, created by Delve Fonts and sponsored by Red Hat.
