Construction of the $2.5 million Upokongaro to Whanganui cycleway - which includes a new bridge over the Whanganui River - will begin next month.
The bridge is expected to be completed by March and will take the Mountains to the Sea cycleway on a new route between Upokongaro and the city.
That section currently runs along the eastern side of the river but has been officially closed since 2015 due to safety concerns as it does not provide cyclists with an alternative to cycling on the road.
When the bridge is complete, the cycleway will cross the Whanganui River south of Upokongaro and run off the main road along the western side off the river until the 50km speed limit at Aramoho.
"The bridge at Upokongaro will take cyclists off the busiest part of the current route and onto quiet trails on the opposite side of the Whanganui River which will lead them straight into the town," Whanganui & Partners destination marketing strategic lead Paul Chaplow said.
