Skyline Locust vs New driveway...

Asked October 10, 2015, 8:12 PM EDT

I have a Locust tree approximately 40ft tall, 20 years old within 8' of a driveway. In recent years about 4 roots have pushed up bumps in the driveway. What are the chances of seriously damaging the tree if these roots are removed during a driveway replacement? Are locusts particularly tolerant or susceptible to root disturbance? Please advise. Thanks, Mark

You certainly risk damaging the tree. You may not see the evidence for three or four years, but the tree will be structurally weaker and will lose access to water and nutrients. As for whether locusts are tolerant or not, they are tolerant. Here is a list:
