Incorrect Routing on BR-116 – Missing Road Restriction Causing Invalid Path

[thiagoferracini]

Issue

An incorrect routing behavior is occurring on BR-116, Brazil.

The routing engine is directing vehicles through an unintended access/road segment, generating an invalid route. This segment should not be used for through traffic and must be blocked/restricted to prevent incorrect navigation.

Currently, without this restriction, the router continues to calculate paths using this invalid access, causing wrong routing results and operational issues.

This is a map data / road access configuration problem, not expected routing behavior.

Steps to reproduce

Request a route on BR-116 near the affected segment.

The routing engine selects an unintended access path.

The route deviates from the correct main road flow and follows an invalid segment.

Environment details (if applicable):

osrm-backend version: Not applicable / external routing service

OSM extract: Brazil / São Paulo region

Processing: Not available

Server queries: Routing request on BR-116 near affected access

Expected behavior:
The routing engine should not allow routing through this access. A road restriction/block must be applied to prevent usage.
