Columbia Gas will begin night work Wednesday evening downtown Steubenville as crews continue to install new gas main as part of the $5 million investment in the city.
Court Alley will be closed from 6 p.m. until 6 a.m.
Portions of Market Street may also be affected during those hours.
Overnight construction hours benefit commuters who will have fewer delays or detours, and business owners who will experience less disruption during the day.
The work is expected to last approximately two weeks.
