[Talk-us] I-69 east west vs north south

[Dave Mansfield]

Tod,

 

This section of I-69 is an exception to the odd numbers being north and south. The official highway direction of the section of I-69 I’m talking about is east and west. All signs for it are also east and west.

 

I understand what you are saying about the official direction is not always the same as the actual direction. There is a place on I-75 near me where northbound is going southwest for a short distance and southbound is going northeast but that is not the case with I-69

I don’t have direct knowledge of I-69 but the numbering on the Interstate system has odd numbers for north-south routes, so having all of I-69 in north and south relations seems correct to me.

 

I have seen area where due to topography long stretches of north-south road actually go east-west. I’ve also seem areas were US numbered highways end up with an opposite compass bearing (i.e. the north bound direction on the highway is actually going south). Just because a section of the route is going in a different direction than the overall route is not a reason to separate it out of the route relation. That is, the route relation should match the official highway direction.

 

Cheers,

Tod

Hello,

 

I-69 in Michigan is east / west from where it splits from I-96 near Lansing  <http://www.openstreetmap.org/#map=13/42.7761/-84.6325> http://www.openstreetmap.org/#map=13/42.7761/-84.6325 to where it ends in Port Huron. It is part Relations that are north and south. 

 

I would like to fix it but I don’t have a lot of experience with relations so I thought I should ask first. Would it be correct to remove the section that is east and west from the north and south relations and create new relations for east and west?

 

Thank You 

Dave
