You will need two routes to the same destination, but they will be pointed to the different T1 next hop IP's.

For example -

LAN1--Router1--T1-1--Router2--LAN2

--T1-2--

LAN1 10.1.1.1/24

Router1 T1-1 10.1.255.1/252

Router1 T1-2 10.1.255.5/252

LAN2 10.1.2.1/24

Router2 T1-1 10.1.255.2/252

Router2 T1-2 10.1.255.6/252

Routes on Router1

ip route 10.1.2.0 255.255.255.0 10.1.255.2

ip route 10.1.2.0 255.255.255.0 10.1.255.6

Routes on Router2

ip route 10.1.1.0 255.255.255.0 10.1.255.1

ip route 10.1.1.0 255.255.255.0 10.1.255.5

This will give you two routes to the same destination so you can achieve load balancing.

You can also decide on how you want the traffic balanced based on the switching method (per packet, per destination etc).

Heres a link on the different switching methods for load balancing.
