Starting with this great bridge approach, plenty wide enough to fit a gargantuan creature it should be a great place to have a showdown with your players. I've also included a bridge up version, with separate bridge png asset. There's also spiked barricades and weapon assets you can use as well.
35x55 Squares
18 Variants (Grid and No Grid options for a total of 36)
The map comes with Normal, Attacked, Bridge Up, Clouds, Creepy, Desert, Misty, On Fire, Raining, with day and night versions of all.
All the maps are under 5mb so work nicely with Roll20 free users.
