So you can't tell steel from concrete? There aren't many alternatives to repairing a bridge over water, except completely replacing it. Those bridges have all needed tens of millions spent on them. The viaducts were there to cross an area of heavy industries. Those have gone now - we can put the road on the ground.
Granville Bridge, for example
1997: seismic retrofit of the north and south piers
2009-2010: installation of over 3,000 steel stirrups to the concrete ramps
2012: repairs to pier M7 at the north end
2013: replacement of the steel truss span bearings
2016: repairs to the gantry system
2019-2021: seismic and structural upgrades.
The Lion's Gate was rebuilt in 1975, and that lasted 25 years until it was seismically upgraded again in 2001. That cost $63.4m (in 2001 dollars - over $100m in today's dollars).
You'd apparently prefer taxpayers to find another $90m (in 2018 dollars) to prop up the viaducts than have them replaced.
