Hood River City Council has given the go-ahead to do engineering work for putting a signal at the intersection of Rand Road and Cascade Avenue.  City Manager Rachel Fuller says since the project was first considered nearly seven years ago, costs for engineering have gone up by about $200,000.  She adds that when it comes time to decide whether to go ahead with construction, there will be cost increases to deal with there as well.  The Oregon Department of Transportation has approved $750,000 towards the intersection project.  A full estimate on construction costs is expected in 2019.
