Building the future
I-84 Snow Zone Safety Improvements
Client: HP Civil
Scope of Work: Drilled Shafts
Project Year: 2020
The Project
The section of I-84 between Pendleton and La Grande is plagued with some of the highest crash rates and frequency along the corridor, making the segment a priority for improvement.
The Solution
Bauer BG 22 H to efficiently drill 60″ shafts, place rebar and 4000 PSI concrete to the construction joint elevation in the plans.
The Result
The I-84 safety improvements added over a dozen new intelligent signs to alert motorists to a wide range of hazards and conditions to reduce accidents and fatalities on this section of I-84.
Project Overview
The section of I-84 between Pendleton and La Grande is plagued with some of the highest crash rates and frequency along the corridor, making the segment a priority for improvement. This project advances some of the recommendations from the Corridor Management Plan (described in Station 2). It focuses on the section of I-84 between Pendleton and La Grande. Design was completed in 2019 with construction taking place in 2020.
The project was funded at $11 million, with $4 million allocated from the 2017 Keep Oregon Moving Transportation Bill.
| Over a dozen new electronic message signs to provide information about: | |
| Weather and roadway conditions, | |
| Chain-up conditions, | |
| Curve warning information, and | |
| General information that impacts the interstate such as crashes ahead, closures, or construction information. | |
| Ten new weather stations with sensors to detect pavement conditions and cameras to provide visual information to operators and travelers. | |
| A dozen curve warning signs with flashing beacons in the Grande Ronde River Canyon (west of La Grande). | |
| Nine miles of cable barrier between eastbound and westbound lanes at two locations to prevent cross over crashes (MP 229 – 238, and 249-250). | |
| Two miles of prep work for future LED roadway lighting along Cabbage Hill westbound curves (MP 221-223); 20 lights will be installed initially with additional illumination as funding allows. The LED illumination will help delineate the westbound lanes through the curves as you are driving down the hill. | |
| An automated ramp gate at the westbound on-ramp from Exit 224, allowing for faster closure during inclement conditions. This reduces the number of vehicles entering hazardous conditions, reduces the likelihood of a crash, and frees up staff resources to clear the roadway faster. | |
| Over a dozen miles of yellow reflective markers attached to guardrail in Cabbage Hill area. | |
| Over 10 miles of buried power line (to support these enhancements and future upgrades). | |
