Travel Time Routes

Travel times are only listed for routes in which congestion levels normally have an impact on the estimated travel times. This generally would include routes heading into the city in the morning and out to the suburbs in the evening. Additionally, the travel times shown on the web site reflect the messages displayed on the overhead message signs.
