• A number of cities (e.g. New York, San Francisco, Seoul) have removed urban expressways with positive neighborhood and real estate benefits
• Remove options are typically around $100 million/ kmremove

• A number of cities (e.g. Boston, Seattle) have elected to replace elevated expressways with below grade tunnels
• Boston replaced expressway with an street level park• Tunnel options are typically more than $1 billion/ km
• A number of cities (e.g. New York, Louisville) have invested in improved lighting and public realm to reduce impact of overhead expressways
• Costs range widely depending if structure is in need of repair
• Many cities (e.g. Buffalo, Washington) have invested in rehabilitating elevated expressways as functional single use infrastructure
• Costs range widely depending on type of construction and local conditions.
