Q. Would CMOS lowercase the noun preceding the number in each below? Yes or no?

He was called to aisle 8.
The meeting was at building 50.
The accident happened on interstate 90.
Tom got off at exit 12.
Holyfield fell in round 4.
The cashier stole cash from register 7.
The incident happened at terminal 1.

Thank you.

A. Words like “interstate” and “highway” are generally considered part of the name and capitalized: Interstate 90, Highway 66. But all the other terms in your list—from “aisle 8” to “terminal 1”—would be treated as generic and lowercased.
