Today, the road runs for about 200 meters in a tunnel, when the in Hämeenlinna was completed in 2014 on the pavement. Attention has also been paid to the aesthetics of the highway environment. Some of the bridges at Highway 3 can be considered almost works of art and the rock cuts have been illuminated. Ekku Peltomäki's light art work "Lux Tavastia" is next to Akaa's Terisjärvi.
