GO Transit Lakeshore West train riders may have to adjust how they get around this month as the transit agency is suspending service on part of the line for three consecutive weekends due to construction work.

A reminder sent out to GO Transit riders Tuesday afternoon said the service suspensions will happen on Dec. 6 and 7, 13 and 14, and 20 and 21 related to the replacement of the Etobicoke Creek rail bridge just west of Long Branch station. Some late-night service on each of the Fridays preceding the impacted weekends will also be affected.

Officials didn’t elaborate on the exact work that will be taking place or why it needs to happen over three consecutive weekends, but added it’s “critical to maintaining safe and reliable service.” They noted that a crane will be assembled near the creek to help facilitate the replacement of the century-old bridge during the winter.

Here’s how GO Transit service will be impacted for each of the weekends:

• Dec. 6 and 7: No service at Appleby, Bronte, Port Credit, Long Branch and Mimico stations, GO trains will run between Exhibition and Union stations on a special schedule
• Dec. 6 and 7: GO train replacement buses will stop at West Harbour, Aldershot, Burlington, Oakville and Clarkson stations
• Dec. 6 and 7: Trains will run between Aldershot and Niagara Falls stations, buses will take riders to Bramalea station from West Harbour and Aldershot stations to connect with Kitchener line trains
• Dec. 13 and 14: No service at Appleby, Bronte, Port Credit, Long Branch, Mimico or Exhibition stations, there won’t be GO trains between Exhibition and Union stations
• Dec. 13 and 14: GO train replacement buses will stop at West Harbour, Aldershot, Burlington, Oakville and Clarkson stations
• Dec. 13 and 14: Trains will run between Aldershot and Niagara Falls stations, buses will take riders from West Harbour and Aldershot stations to Bramalea station to connect with Kitchener line trains
