Lead. A 100-metre pedestrian and cyclist crossing between Lillestrøm and Strømmen, designed to close a missing link in the riverbank's green-mobility loop without taking the river over. The brief asked for a connection; the design problem was how to add a major span to a quiet stretch of water and make it feel like almost nothing has been added.

Site & brief. Lillestrøm and Strømmen face each other across a hundred metres of river, separated by a gap in the bank's continuous walking and cycling network. The municipal competition asked for a permanent pedestrian and cyclist bridge sized for everyday traffic — part of a wider urban development strategy to strengthen green mobility along the riverside and tie the two districts into a single riverbank walk.

Idea. A bridge that doesn't stand in your way. A lightweight steel girder box does the structural work — a single slender main beam riding low over the water on a double-strut pillar, kept to a profile thin enough to read as a line on the river rather than a structure planted across it. The deck curves in a gentle S in plan, following the natural lines of approach on each bank instead of cutting straight across — the structure deferring to the river rather than dominating it.

Resolution. The two ends are deliberately asymmetric. On the north bank the bridge touches down lightly on a double-strut support, leaving the existing landscape almost untouched. On the south — where the quay already carries weight — it lands on a substantial abutment that doubles as public space: a timber amphitheatre stepping down to the marina, sheltered above by the bridge deck, turning the riverbank into a place to linger. Mid-span, the structural spine splits and the deck widens into a vista point, giving people a reason to stop in the middle of the crossing rather than just pass over it.
