This is both a resource pack and a demonstration mod which through a plugin replaces some stone bridges across Skyrim, especially bridge01 and bridgelong01 with wooden versions. The meshes are named differently so as not to affect the vanilla bridge meshes.

Constructing them from mesh pieces in Bodyslide's Outfit Studio, the wood bridges use vanilla (read: stone) bridges as a base, by aligning parts of the bridge to conform with the originals' collision planes. The bridges are also have been UV-mapped to use mine scaffold textures, as well as to match the existing navmesh.

During testing, there revealed to be little to no effect to overall gameplay performance while using the meshes.

ADDITIONAL INFORMATION FOR ENHANCED LIGHTING AND FX USERS:

The mod also includes null meshes when using ELFX Exteriors to remove bridge shadows; in Mod Organizer, move the mod after Enhanced Lighting and FX.

CAVEATS: 

As a consequence, however, because these bridges are enclosed within the collision shapes, there may be some objects and NPCs floating slightly on the bridge deck, why projectiles cannot pass under guardrails, why the player can't sit in the framework, or why the player can run along the guardrails as if floating mid-air.

That's just changed recently, as the bridge meshes have been improved by running NIFUtils Suite to regenerate their proper Havok collision, including the ability to sit or stand inside the framework, jump onto the pilings, or firing an arrow through openings.

INSTALLATION:

The mod is packaged as loose, to be intended as a modders' resource. Either use your favorite mod manager to install, or extract the file's contents into the Skyrim directory.

UNINSTALLATION: 

Before uninstallation, get into any interior cell and make a gamesave.
