What Happens to Traffic When You Tear Down a Freeway?

• This video discusses the impacts of highways in urban areas of Seattle, Portland, and San Francisco, particularly when they are removed.
  
• Students will learn how the interstate system that was built in the 1950s led to the construction of freeways in cities across America, but that removing freeways in Portland and San Francisco has had a positive impact on reducing traffic.

Positives

• This video challenges students to think critically about transportation in urban areas.
• Many helpful links can be found in the video description area.
  

Additional Prerequisites

• Students will need to understand what a freeway is and how it is different from other roadways.
• The video briefly notes that freeways hurt the environment, destroy urban neighborhoods, and increase segregation without offering an explanation. Students will benefit from understanding why freeways have negative impacts on communities.

Differentiation

• History and social studies classes could watch "How Highways Wrecked American Cities" (linked in the video description) to learn about the racial motivations behind the location of urban freeways, then follow it with this article that details how removing freeways can lead to gentrification.
• Social studies, science, and design classes could use this video to start a discussion about the role that urban planning plays in promoting livability in communities. Have students make a list of forms of transportation and then think about how urban planning can facilitate modes of transportation that are better for the environment.
• Social studies and economics classes could discuss the concept of induced demand mentioned in the video and think about other situations that this concept might apply to. 
  
• Other resources on this topic include this video that shows the value of getting around without a car, this video on bicycle-only roads in the Netherlands, and this Grist video on walkable cities.
