Network distance from multiple origin points to nearest highway

I need to calculate the distance from a number of census tract centroids (origin - which is a point shp file) to the nearest highways spread around the city (destination, a polyline shp file) using the street network as line class (in a third polyline shp file). (It's to calculate distance to the nearest highway from multiple origin points).

My destination (highways) are also part of the street network and identified by a field, so I can also use the same file (network) for both the route as well as the destination.

I have tried to set up OD cost matrix in Network Analyst but it requires the destination to be a point feature class (whereas in my case, it's a polyline, where the solution needs to find the shortest route using the street network). So, I'm really not sure how to go about this.

I've been told that it's a common feature to calculate network distance to highways, so I'm hoping that someone has already done this and know a way of doing it.

It'd be great if anyone can help with this.

Many thanks in advance!!
