The county has another roundabout.
The County Road 23/McIvor Road/Fort Hill intersection improvement project is mostly complete.
Barricades that limited vehicles to local-only traffic have been removed.
The project started in early June and finished slightly behind schedule, the county said on its website, due to early wet weather, delays in getting overhead utilities relocated and a shortage of some granite curb materials.
The county said the work included transforming the two-way stop-controlled intersection of County 23, McIvor Road and Fort Hill Road into a modern roundabout.
