Going downtown to run a quick errand? Starting on Wednesday, the city is adding 15-minute parking meters for that reason.

According to the city, the meters will be clearly marked and located in the middle of each block, with two meters for both the west and east sides of Massachusetts Street.

A quarter will pay for the full 15 minutes.

There are currently seven free 2-hour lots and 10 metered parking lots downtown with 2-hour, 5-hour and 10-hour meters, according to Parking Control.
