The Gardiner is reduced to 2 lanes (was 3), the speed limit is lowered and it is causing huge traffic jams. Eglinton is still open, though there might be intermittent closures sometimes, but the construction is causing a big mess (like narrowing from 4 to 2 lanes in random places, equipment blocking parts of the road, pylons everywhere), various side streets are closed off at times, etc. This is to build underground LRT, which is rather like subway except the eastern end will run in the median of the road and it has 1/3 of the capacity of subway (due to the bizarre municipal politics in Toronto). Since OSM has no real time traffic data this is somewhat limited, but if I am going from near Yonge and Eglinton to somewhere west of Toronto such as Mississauga, invariably the router will tell me to go west on Eglinton then north on Allen then west on 401. This is an awful route. It is better to go north on Yonge or Avenue then west on 401 (though if the 401 is jammed which it usually is then it is better to take Lawrence). A router ought to avoid driving on roads tagged construction=yes, not sure how much it should penalize them.
