I need to find the shortest distance between three towns, and suggest the cheapest cost to build a pipeline that will cross these 3 towns. I have 25 towns total and data for each of them: roads and cost based on lenght. I want to know if it is possible to solve this with network analyst since I had tried and I have to enter an start and end point (or an incident). In this case a don't have references, only points (or the towns locations). How do I do this?

Data: 25 towns locations
Road network between towns

Need: shortest distance for 3 towns out of the 25 towns
the cost wil be based on the length of the route.
