The bridge connects two gravel roads (quite well maintained) and is the best point to cross aura if you are biking from Ravattula towards Haaga and further north.

Partly normal bike path running alongside the highway, partly unpaved side roads with roadbike-doable gravel (apart from the continuous reminder of your status as a second-class road user); the highway itself is fairly busy and a bit narrow (shoulder barely wide enough to ride on).

Not too bad, asphalt showing its age (the usual crosswise cracks every few metres) in many places though
