Why is the new bridge designed only to achieve a Level of Service (LOS) D?
The proposed new facility would be designed so that during most times of day the level of congestion will allow traffic to flow. During the peak morning commuting hour, the bridge would experience heavy traffic flows without excessive delays. In other words it would operate at LOS D. This is an improvement over the current breakdown conditions (LOS F) experienced during peak travel times on the existing bridge.
