Ive had mostly OUTdoor/INdoor cats - who have lived 20 years this way. And indoor cats who have had just as many vet bills. BUT on a busy road, you are taking your chances. Cats will wander that far, sometimes chasing something or being chased. If possible, Id try to build one of those outdoor inclosures. You can find DIY homemade versions on the net, using scrap materials even. Good luck. Ultimately its your choice - just have to weigh the risks.
