Detour information for transit appearing in Google Maps

It seems that Google Maps is testing something new: temporary detour information.

See these results for TriMet:

I’m assuming the information is collected through TriMet’s Web Services API.  There are several calls for requesting current detour information.

Does anyone know if this is being tested for other agencies?
