I would make sure your car is within the marathon route. Since the hospital is within the route, crossing over would take the longest or may not be possible depending on timing. Normally there is a guide that goes out that gives approximate times that runners will be at each mile. Maybe someone else can link it because I haven’t seen it yet.

in addition to what the other commenter said, you might consider getting a hotel or airbnb for the day. if you can afford it, it would eliminate all worry.

Considering the traffic we got stuck in as nurses during the cycling event last month or so, it took an hour to get there and I like a mile away, Definitely plan ahead, the traffic control in the city was non existent then.

I'll be honest, you're pretty in that bubble and just looking at the map (https://www.arcgis.com/home/webmap/viewer.html?webmap=06f2959e05c24bbebf51fe476eb369c1&extent=-76.6617,39.2789,-76.5349,39.3279), I don't have any great directions for you.

My best advice would honestly be to find an AirB&B (or a friend or someone you can stay with) somewhere in Butchers Hill (you don't want to have to cross Linwood) during that time. Maybe also talk to your OB to see if they know of any resources Hopkins may have (legit no idea, I just know there aren't any hotels super close).

Don’t hesitate to call an ambulance if you are stuck!!!

Thank you for posting this map. Based on this we're inside the bubble with Hopkins so we should be okay.

Plan ahead. The ambulance response times get messed up by it too.
