Two tunnels (the Midtown and the Downtown) connect Norfolk and Portsmouth and thousands of vehicles travel through them daily.A passenger car that travels through one of these tunnels during peak load hours pays $2.33 (one-way).When the tolls were first imposed in 2014, the number of vehicles traveling through the tunnels plunged by about 30%, but since has recovered to almost the pre-toll level.Use economic analysis to explain why many drivers decided to pay the tolls.
