Lara Croft Way is only open in one direction at the moment so its currently not possible to drive from the Osmaston Road roundabout to the Babington Lane Roundabout. The outbound section of Lara Croft Way is due to open in two months. Charnwood Street will then become a cul-de-sac.
I was one of the first few to drive along Lara Croft Way on Tuesday morning at 7:10am, It felt strange being able to cut out the bit down Normanton Road and Leopold Street, It was about 3 minutes quicker than going the old route. At busy times it would probably save even more time than that. All we need now is for Mercian Way to open and that will help make it quicker still.
Here is a map showing the exact route of Lara Croft Way in Derby :

Mercian Way will be the next section to open up, looking at how its going I would imagine that the section from the top of Babington Lane down to Abbey Street will be the next to open to traffic.
