What should I put for my work location if I was between two locations. 50% of the time, I worked at one location outside of the city that is listed on my W-2.

I am not sure what to do with the address for my workplace when it comes to taxable income within my city. I work for a hospital system where I go to two different locations, 50% of my time spent at each. One hospital is located at the address listed on the W-2, the other facility is outside of that city. I am not sure if the address matters, or if it would be beneficial to say the address is the location of the second facility.

You should use the address (locality) that is on your form W2.  The local income and taxes in boxes 18-20 should represent the portion of your income that was earned/paid in that locality.  You may cause a filing error if you report one via your W2 entries and another via your state/local interview.  There would be no advantage; the local taxes were withheld/paid already.
