Temporary Road Closures is a full-stack, AGPL-licensed platform built during Google Summer of Code 2025 for the OpenStreetMap Foundation. Community users can submit closures via a responsive Next.js/Leaflet interface, while a FastAPI service backed by PostgreSQL + PostGIS validates, stores, and serves geospatial data. The system encodes locations with OpenLR to remain map-provider-agnostic and exposes a documented REST API for third-party integration. A Valhalla integration powers closure-aware routing across auto, bicycle, and pedestrian modes, with side-by-side route comparisons. Security and reliability are addressed with OAuth2/JWT auth, rate limiting, CORS, and containerized deployment (Docker, Nginx). The result is a scalable, standards-compliant foundation for real-time navigation intelligence in the OSM ecosystem.
