Is it possible "to select" some interval on roads layer?

Dear Gurus!

There is some roads layer. How can I highlight a section (from point to point) of road under repair?

(I use wpf API in c#)

in any application within arc, the desired selection would have to be from already segmented features or a new one would have to be created. If you want to go 75% along an existing polyline, then it would have to be created, there are no tools to just select a portion of a line and show it without creating the feature first

Can I create some line feature (by using some API method) from segment of road to show on some Graphic layer?

Or it is  reasonable to create points at the beginning and end (or middle) section of repairs?
