Collins Corner is a signal controlled fiveways junction on the B1, to the east of Downpatrick. The junction is named after the Round House bar, which has a large sign reading Collins on the aspect facing the town.
The junction was remodelled in 2017[1] alongside the move of the hospital to a new site on the outskirts of the town. As part of this, some traffic priorities were changed, including making Stream Street (south) one way away from the junction, and providing a left filter lane for Pound Lane traffic heading onto Killough Road.
