LHTAC is pleased to announce that we’ve recently hired two new employees to fill our vacant staff positions. They will be working as part of the Federal-aid Design team, covering separate regions of the state. Our Federal-aid Engineers assist Local Highway Jurisdictions (LHJs) in preparing projects and applications for submission for federal funding participation, provide project administration and oversight of consultants, contract bid documents and documents for constructing transportation projects. They are also responsible to assist LHJs with technical assistance and provide resources relating to their transportation issues. (more…)
Public Comments on LHTAC’s Funding Applications will be taken March 14-28th.
The Local Highway Technical Assistance Council (LHTAC) will be accepting comments and suggestions for improvements on our current funding applications. Areas open for comment include: the application process, format of applications, questions/scoring etc.

Project Description: The project is located on Turner Road, a farm to market road approximately 0.2 miles west of Grace, Idaho. The Turner Road Penstock Bridge carries Turner Road over eleven foot diameter wooden penstock enclosed pipe that feeds a PacifiCorp owned power generation plant. The penstock is four and one half miles long beginning at the Grace Dam Complex on the Bear River and ending at the Grace Power Plant.
The Turner Road Penstock Bridge was closed to all traffic due to structural deficiencies. The bridge consisted of two arch pipes founded on concrete and pile foundations with concrete wing walls containing the roadway fill over the arch pipes. The concrete wing walls were severely deteriorated with large open, working cracks and pushed out of alignment. Should a large portion of the wings break off and land on the wooden penstock, it is expected the penstock would crush. The result of this damage would be a total loss of the entire penstock.
This project consisted of reconstructing Turner Road Penstock Bridge with geosynthetic reinforced soil integrated bridge system (GRS-IBS) technology.
Status: The project is currently in construction and about 90% complete. The anticipated completion date is spring 2016.
