Routing API ignores closed roads - here-api

Question

I'm testing the routing API and I'm wondering why it creates routes through closed roads.
There is my request: https://route.ls.hereapi.com/routing/7.2/calculateroute.json?waypoint0=geo!50.01568168937738,20.901489257812504&waypoint1=geo!50.0155162303763,20.879259109497074&apiKey=API-KEY-HERE&mode=balanced%3Bcar&alternatives=0

The proposed route looks like that:
route through the closed bride.
The road closure info is available in the map. I've checked that in the Map Creator. Here WeGo map also knows about this and suggest an alternative route:
the valid route from Here WeGo.
Is there something wrong with my request?

Answer 1

Please try using following combinations for mode in your rest call. The Routing API v7 supports the following valid parameter combinations for routing modes.
Traffic-enabled:
mode=fastest;car;traffic:enabled
Traffic not enabled:
mode=fastest;car;traffic:disabled
mode=shortest;car
Also refer : https://developer.here.com/documentation/routing/dev_guide/topics/routing-mode-parameter-combinations.html
Please connect even if this doesn't result to what you are expecting the output to be
