Congestion Pricing on Legacy Roadways

What happens when there is no room to widen a congested roadway? One solution is to build above the roadway. Another, suggests an HNTB expert, would be to convert an existing lane into a managed toll lane and fund transit with the revenue.

"Some of the most chronically congested highways in the Northeast are old legacy roads, which are not tolled and which have no space adjacent to them for building a new toll lane," writes Tom Curry of the Transportation Policy Hub at CQ Roll Call.

One solution was offered by Pennsylvania Secretary of Transportation Barry Schoch who "speculated last year about putting a deck on top of the existing Schuylkill Expressway and offering drivers 'a choice of what they’d be willing to pay, a fee, to get to from King of Prussia to downtown in guaranteed to 20-minute time frame'.”

Other jammed legacy highways throughout the Northeast face the same space constraints as the Schuylkill.

We discussed this with a tolling expert who just moved from California to Arlington, Va., Matthew Click, director of priced managed lanes for HNTB Corporation, a consultant to toll agencies.

According to Click, "(t)he majority of the priced managed lanes are in Florida, Texas, California and Georgia, and were originally conversions of high occupancy vehicle lanes. In the Washington-New York-Boston corridor, congestion pricing is being used only on I-495 in Virginia."

“Let us take the top ten urban areas, and pilot doing a lane conversion of a GP [general purpose] lane. Let’s put performance measurements around it that it has to meet” and regulation so that the toll revenue “doesn’t cross subsidize a convention center or something.”

Interestingly, he suggests spending toll revenue on bus rapid transit or express buses for the corridor.

What Click does not suggest is adding congestion pricing, where the price increases with the level of congestion, to toll roads with fixed rates.
