NEW CASTLE, Del. — The Delaware Department of Transportation is blaming a bridge designer for errors that sent a bridge project over budget and schedule.

The Delaware 141 bridge finally reopened on Monday after the project ran nearly four months over schedule and $1 million over budget. Agency spokesman C. R. McLeod says the department has filed an errors and omissions claim against Philadelphia-based designer McCormick Taylor. The company had no immediate comment when contacted Wednesday by The Associated Press.

Contract documents obtained by The News Journal though an open records request allege that underestimated costs of materials and the blueprints left out a critical bridge support item as well as the existence of an asbestos-covered conduit buried under a sidewalk.

This story has been corrected. The Department of Transportation is pursuing an internal claims resolution process, not a lawsuit.
