I find it very hard to believe your Transport dept. doesn't have a GPS which follows commercial vehicle routes. While truck GPS devices are expensive and not something your team needs to invest in there are also apps available for both Android and IOS.
After a quick google map it looks like your hotel is close enough to Hofstra that buses can run locally and not have to jump on the Meadowbrook. It may take you a few minutes longer but you should be able to find an alternate route and locally should be fine because buses don't follow the same weight restrictions as trucks.
If you aren't able to figure something out with them, call your hotel or Hofstra's shipping dept. and ask if they're familiar with the routes their vendors are using.
I live with a truck driver who delivers in LI so I can guarantee there are ways around.
