Workers laid new asphalt, drilled manholes and striped the roadway.
The road work cost about $1.3 to $1.4 million — roughly $400,000 to $500,000 less than expected, Lough said.
After almost five months, work on Derr Road finished ahead of schedule.
Construction — consisting of removing the top three inches of asphalt, installing a new sidewalk and curb and installing Americans with Disabilities Act ramps — started on April 10 and finished last week, Valerie Lough, Springfield community information coordinator, said. It was 21 days ahead of schedule.
