• 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.
