Problem:
I have a network with 3 routers (1 to Internet, 2 to Corporate) and need an additional layer 3 switch to be programmed to route the traffic appropriately. The two corporate routes serve different purposes and use different carriers, but one needs to fail over to the other. So far I have been unsuccessful in doing this.
Scenario:
Router 1 used to be the default route for the workstations and is the main WAN router for the corporate data traffic. The IP address is 10.0.82.1/24.
Router 2 is a new router establishing application-specific traffic to the Corporate office and if this one fails, the traffic needs to be sent to Router 1. Currently, this failover does not work as attempted. The IP address is 10.0.82.203/24.
Router 3 is actually a simple firewall that connects to the internet router and then out to the internet. By design, all traffic that is not explicitly intended for the Corporate office goes out this way to the internet. The IP address is 10.0.82.2/24.
New Layer 3 Switch --- Cisco 3650 --- was configured like it shows below, I have tried to add additional failover routes with different metrics and I have tried changing the gateway from Router 3 to Router 1 to try to force the traffic out& but surprisingly that did not work. The IP address is 10.0.82.18/24.
Also all routing is static. Routers 1 and 2 are managed by someone else and do not have any dynamic routing enabled. Part of the reason for my trouble.

So if I want traffic going to 10.0.82.203 to be sent to 10.0.82.1 if the Router 2 fails how do I do that?
Thank you so much for your assistance.
