The Marine Management Organisation (MMO) has granted a marine licence for the planned refurbishment of Newcastle's Tyne Bridge, subject to several conditions
With the River Tyne being tidal for its last 14 miles - fish migration, including Atlantic salmon, was a concern with the work lasting up to four years.
It was feared that any lights pointed directly at the river could cause behaviour change among fish and impact migration required to spawn.
In addition, with restoration including the removal of guano as well as steelwork blasting and repairs - both the scaffold and gantry will be fully sealed. This will protect against the release of fuels, oils and chemicals into the river.
Should any oil, fuel or chemicals leak into the Tyne, this must be reported to the MMO within 12 hours so the risk can be managed and minimised for the marine environment.
The Grade II listed structure was last refurbished and painted in 2001 with a paint system designed to last approximately 18-20 years.
The current work will include steelwork repairs, full re-painting, concrete repairs, drainage improvements, stonework and masonry repairs, bridge deck waterproofing and resurfacing, parapet protection and bridge joint replacement.
The aim this time is to future-proof the bridge requiring it to need less maintenance in the the years to come
