>>3352612> its been really well blocked off now.
Most of the old tunnels have been re-secured in recent years. Back in the day I walked from Botanics to Maryhill, Botanics to Kelvinbridge (behind the Big Blue) and from Gibson Street to SECC.
Maryhill tunnel was sealed during housing constructions.
Pub at Kelvinbridge has used another tunnel part for seating
Gate at Gibson St was reinforced.
So good luck to any ex/p/lorers.
There was an unused government control centre under the Central Hotel which you could get into either through hotel or under the railway bridge from river side.
