Drivers who commute 30 minutes a day lose around 22 hours annually due to traffic, according to a report by the American Association of State Highway and Transportation (AASHTO).

The AASHTO report, ‘Unlocking Gridlock,’ claims higher travel volumes and limited roadway capacities are creating traffic problems in the country.

AASHTO’s executive director, John Horsley, said trucks move 93% of the freight in the US and is likely to handle 95% of it in 30 years.

“About 95% of the US’s passenger travel occurs via highways,” Horsley said.

Calling for an expansion in highway systems, the report estimates that annual travel will reach 4.5 trillion miles by 2050.

Nearly $175bn is required for highway investments, according to a US Department of Transportation report released this year.
