Yes it is bad.
To ease backups around the topside of the beltway to Route 43, shoulders will become travel lanes.
That sounds like a good idea except for that if there is a breakdown or accident, with no shoulder, were is someone to pull over to?
Decades ago Maryland had a plan to extend 29N to the Baltimore Beltway but Howard county opposed it and one of the HC planners told me that without the county’s cooperation the state would never get the Feds environmental permission to build across the Patapsco park (near Daniels Area) and the river.
The State dropped it a few years ago and another neighborhood was built where a forest was on the North side of Rogers Avenue near 29 where the extension would have been.
When I did have to go from 70E to 695N I would go all the way to the end of 70 (left lane) and loop around the parking area to bypass the twin bridges to take that exit North.
I am guessing that messing with the bridges there is way more expensive than Hogan can get $$$ for and might have even shut down the entire pass-way till it was completed (I am no expert)
If an accident happens as you say traffic can go either South or further East and take a U turn as I have done many times.
