This type of road design provides for better overall access to the street grid than a grade separated freeway. A boulevard separates local traffic from through traffic while still allowing for flexibility during congestion. This benefits motorists who can easily change their route during backups. This is ideal for busy urban corridors. For elevated freeways, due to limited access to local streets, traffic cannot readily adjust when needed. Also noted during the discussions was that during heavy traffic, travel times on the boulevard would be comparable to those of a backed-up elevated freeway. This suggests there was no benefit to replacing an urban freeway with one of the same limited access design.
