what is lanelet ?
duplicated relations and way !

Please check topology of "Main Street" (length over all) with presumably connected side roads.

Boston River Run

Can someone confirm and add if here is Cooper Gallery of African & African American Art?

There is a no-straight-on turn-restriction in this junction which I cannot verify through Mapillary images. Can someone verify this restriction and update whether it is present or not.

Thanks

CAn anyone verify if this road allows cycles? Thank you!

There should be turn restrictions here so that OSRM doesn't try to route e.g. a right turn at this intersection.

Eric & Liz's House

there seems to be a bridge here and a stream flowing underneath
