Road construction is often messy, inconvenient, and loud. While access to driveways will be maintained during construction, expect a rough ride and travel delays getting through the project area. In your yard, only a minimal amount of digging for the widened portions of road is necessary. The contractor will instead use a cement stabilization material in the subgrade of the road surface. The contractor is responsible for moving and replacing mailboxes. Any other obstructions you may have will be reviewed case-by-case.
