Mogu da se postave plastične providne barijere (koje imaju nalepljenu po koju pticu grabljivicu da ne bi obične ptice srljale i ginule), takođe postoje određene vrste asfalta koji smanjuje buku.
To je jedno od puno razlicitih resenja za autoputeve, standard...osim kod nas, naravno. Koristi se najcesce na starim autoputevima koji su gradjeni bez ovih barijera, jer je jedno od najjednostavnijih resenja.
Posto se ovde radi o potpuno novom mostu, sistem zastite od buke bi trebao da bude sastavni deo projekta mosta.

Noise Walls on Bridges
Structural:
Consider weight stress and rotational loading.
Consider bridge vibrations due to existing traffic.
Consider bridge vibrations from construction operations.
Consider the impact of any parapet attachments.
Consider the type of anchoring system.
Consider top of barrier profile if the top of parapet profile is not smooth and/or consistent.
Safety
Ensure protection of traffic (both on and beneath bridge).
Consider the potential for damage and injury in the event of the noise wall or parts thereof falling from the structure.
Ensure adequate vehicular sight distance.
Consider barrier shading resulting in highway icing, and adverse effects on highway lighting.
Maintenance
Consider accessibility.
Consider snow drifting and storage implications.
Consider possible restrictions to bridge inspection teams.
A treba spomenuti i toliko hvaljenu "lepotu"
mosta...
Sto se tice plovnog puta i klirensa ispod mosta...pa to je vec poodavno definisano dimenzijama postojecih mostova i dubinom korita Save.
Kao sto vec rekoh u jednom od pethodnih postova - neće nosač aviona da plovi Savom.
