Track and tunnel repairs along the northern portion of the Yonge subway line might make things inconvenient for late night riders over the next two years, beginning Sunday night.

The TTC will shut down the Yonge line between Eglinton and Finch stations at midnight for six days a week until late 2010. Everything will re-open in time for the morning rush, so the closure affects trips between midnight and closing time, around 1:30 a.m. every day but Saturday night/early Sunday morning.

Shuttle buses will replace the subway service during the maintenance hours.
