We have PennDOT which is run by idiots.They have stupid rules which makes highways more expensive and take longer to complete. I'll give you an example. Our town had an open grate bridge. 4 of the 8 beams were shown to have significant corrosion. Our engineers suggested replacing all 8 since the other 4 were also showing signs of corrosion and we had to take the deck off anyways. PennDOT said no. They wanted us to replace 4 beams, take the other 4 and refurbish. When we bid the job, the contractor said he would put in new beams for the same price as refurbing the other 4. PennDOT said no again. When we asked them why, they said if we replaced 4,it would be a maintainence project. If we replaced all 8,it would be a construction project.Who cares what you call it? Common sense would say you would replace all 8 and be done with it.
