way/1164101202 (T4 / Traforo del Frejus approach): maxweight=11.5 appears incorrect. This is a mandatory approach segment of the Frejus road tunnel, which carries international HGV traffic up to the standard 44 t; an 11.5 t limit here would legally close the tunnel to nearly all lorries, and routers honouring the tag divert trucks over the Col du Mont Cenis hairpins. We could not find such a limit signed on the ground or in tunnel operator documentation. Suggest removing maxweight=11.5, or correcting it to the signed value if one exists. - MapMap navigation data team (verified via routing diagnostics, 2026-07-17)
