Tennessee Department of Transportation Commissioner John Schroer's seventh floor office in the Tennessee Performing Arts Center at 6th and Deadrick offers a panorama of Nashville's north side.
Below the high vista, cars on Interstates 40 and 24 appear like miniatures moving across a diorama.
It's an instructive perspective for the head of the department tasked with maintaining the state's transportation system and now putting more money to work as Tennessee's gas tax is set to increase on Saturday.

What's the IMPROVE Act?
An acronym for "Improving Manufacturing, Public Roads and Opportunities for a Vibrant Economy," the IMPROVE Act increases the tax on gasoline and diesel fuel. It also reduces the tax on groceries, along with reductions in other business taxes.
The IMPROVE Act lists about $10.5 billion worth of projects in all 95 counties, and increases the state's transportation budget about $248 million annually.
The increase is about a quarter of the roughly $1 billion in projects the department rotates through annually. TDOT Commissioner John Schroer said the department has between $2.5 to $3 billion in projects regularly underway.
How much is the tax now?
The state's tax on gasoline now is 21.4 cents per gallon. On diesel, the tax is 18.4 cents per gallon.
How much is it increasing?
The legislation increases the tax on gasoline by 6 cents per gallon over the next three years. Starting Saturday, the tax will go up by 4 cents per gallon, with additional 1-cent increases in 2018 and 2019.
For those buying diesel fuel, the legislation increases the tax by 10 cents per gallon. Starting Saturday, the tax goes up by 4 cents per gallon, with 3-cent increases in 2018 and 2019.
What about the tax on groceries?
Sales tax on food will be cut from 5 percent to 4 percent starting on Saturday.
