The issue associated with moving the main road toward the shop access road is that it would create an artifical angle which could cause some truck routing softwares to think the turn radius is very large, when it is not. It is preferable to keep the main road angle as close as the real angle as possible. I understand that adding the connection between the main road and the shop access road is artificial too, but it concerns a less important road (the service road). Can you explain how this intersection was tagged as problematic? The service road has the access tag set to "customers", which should make sure routing engines do not use it for through traffic. Please explain which bug/issue this configuration caused exactly in your software suite. Thanks!
