NEW YORK (PIX11) – Folks who rely on the F and M lines should plan on a longer commute as the MTA begins projects that will cause service changes through next year.

Construction on the tracks began Monday and is expected to continue into 2024. The station that will be impacted the most on the M line is the Forest Hills-71st Avenue station, where the MTA will be taking subway cars off the tracks from 6 a.m. to 9 p.m.

Service on the F line will be pushed over to the E line in both directions. Rush hour service will also be reduced, according to the MTA.

A shuttle train will service Roosevelt Island to get people to either Manhattan at Lexington and 63rd Street or Queens at 21st Street, but it will only run every 20 minutes and service stops overnight.

The MTA promised that the construction would lead to improved reliability, but for the time being, it could be a rough ride for about 150,000 daily commuters who depend on the service.
