Traffic to go up and away – The Sun
Now that the Springfield Interchange is completed in Virginia, Maryland is playing catch-up when it comes to complicated interchanges between I-95 and a beltway. North of the city, the I-95 (John F. Kennedy Memorial Highway)/I-695 (Baltimore Beltway) interchange is being rebuilt with “skyramps” to carry High Occupancy Toll (HOT) lanes. Total cost: $450 million to $500 million.

The existing interchange is essentially a directional T (Kurumi) that has been doubled up. Fun fact — all the thru lanes at this interchange cross over the opposite lanes, so the oncoming traffic is briefly on the right side.

I’m skeptical of HOT lanes in general and since these are only 10 miles long, I have to wonder if they will just complicate matters even more. Those two HOT lanes will be have to merge with four lanes of through traffic (around milepost 72) which then go down to three lanes around milepost 77.

I’ll be passing through there this weekend so I’ll note if there is anything interesting at that interchange.
