Wheatstone Bridge for ADC input

Wanting to use a Wheatstone bridge for measuring an RTD sensor but the ADC input can't be used between the two voltage dividers as only one input for ADC.
Thought about different solutions such as adding a resistor to each voltage divider junction the using the one connection foir the ADC input?
Found a good Wheatstone reference but how to utilize for ONE ADC input?

Use a differential instrumentation amp to convert the differential bridge signal to the single-ended signal needed by the ADC. There are also some ADCs that have a differential input.
