The Idaho Transportation Department is designing several upgrades to Idaho 69 (Meridian Road) between the cities of Kuna and Meridian. The project is expected to improve safety and traffic operations on this busy corridor.

Improvements will include:

• Resurfacing ID-69 (Meridian Road) from Orchard Road in Kuna to Overland Road in Meridian.
• Adding traffic signals at Hubbard Road and Lake Hazel Road.
• Installing a median barrier between Calderwood Drive and Overland Road.
• Reconfiguring lanes at the intersection of Meridian and Overland roads. Northbound Meridian Road will include three through lanes, a dedicated left-turn lane and a dedicated right-turn lane at the intersection.

For improvement details and maps see the ID-69 project fact sheet.

Background

Idaho 69 is one of the primary routes between Kuna and Meridian. As growth in the area has increased, traffic congestion and crashes have also increased. In the busiest locations, crashes have increased by nearly 50 percent over the last five years.

Based on a recent safety analysis and input from the city of Meridian, ITD identified several ways to immediately improve safety and traffic flow along the corridor. The improvements were developed in collaboration with the Meridian Transportation Commission, Meridian Police Department and Ada County Highway District.

The safety improvements will be timed to occur with ITD’s planned maintenance on this corridor. Construction is scheduled for the summer and fall of 2018.

For more information

ITD welcomes public input and is committed to working with the community during this project. Questions about the design plans can be directed to Jennifer.Gonzalez@itd.idaho.gov or (208) 334-8938.

The completed plan will include:

• A 10-year plan for the corridor.
• Identification of corridor priorities.
• Identification of existing and projected environmental, roadway, and land use conditions.
• Analysis of future travel demand and performance in the corridor.
• Analysis of accidents and recommendation of safety features including access management.

Sample urban and rural cross-sections of the highway will be illustrated. Any projected capacity improvements that require a cross-section different from the current samples will also be illustrated.

Features will include:

• Number of lanes
• Lane width
• Shoulder width
• Side slopes
• Curb, gutter, and sidewalks for urban cross-sections

The National Environmental Policy Act (NEPA) requires that an environmental review be completed before right-of-way can be acquired with federal funds. The U.S. 20/26 Corridor Study is not programmed to recommend or fund purchase of right-of-way. Therefore, ITD will not complete a NEPA-level environmental review. However, an Environmental Scan will be conducted to provide a baseline survey which includes a qualitative analysis of the current human environment. The human environment includes aspects of the natural environment, built environment, and human health. Constraints that may have a limiting factor in roadway width and placement of the highway section will also be identified.

U.S. 20/26 is a major farm-to-market road serving agriculture and quarrying industries in western Canyon County. Cross-state access is directly provided to Nyssa and connecting access is provided via Highway 18 to Adrian, Oregon. The majority of the highway is two-lane rural with a 65 mph speed limit.

The Idaho Transportation Department (ITD) is studying Idaho 55 to identify current and future needs throughout the corridor. The study will result in three corridor plans (North, Central, South) that identifies policies and projects important to the development of this major arterial over the next 20 years.

ITD hosted public meetings in Cascade, McCall and New Meadows in January 2016.

• January 2016 – Hold public meetings to gather input on the North Corridor
• February 2016 – Finalize Central Corridor Plan
• Spring 2016 – Draft North Corridor Plan
• Summer 2016 – Finalize North Corridor Plan

The Idaho 55 highway corridor originates 1.7 miles south of Marsing in Owyhee County at the Idaho/Oregon/Nevada junction with U.S. 95 and serves six counties, ending at the junction of U.S. 95 in New Meadows. Most travelers know the highway for its turns along mountain forests, whitewater rapids and favorite recreation spots. The corridor is an important route that supports the regional daily commute, the long-haul trucking industry and recreational traffic.

The completed study will include three separate corridor plans:

• South Corridor Plan – ION Junction in Owyhee County to Interstate 84 in Canyon County
• Central Corridor Plan – State Street in Ada County to Banks Lowman Road in Boise County
• North Corridor Plan – Banks Lowman Road in Boise County to New Meadows in Adams County

The Idaho Transportation Department (ITD) is studying U.S. 95 from the Idaho border in Owyhee County to Pinehurst at the Adams / Idaho County line. The study will result in a corridor plan that identifies important improvement projects over the next 20 years.

The plan will be published in three parts:

• North: Weiser River to New Meadows
• Central: Nyssa Junction with 20/26 to Weiser River
• South: Oregon State Line to Nyssa Junction with 20/26

U.S. 95 runs north to south through western Idaho. It provides an important north-south international transportation link for long-haul freight between Mexico and Canada.

Within the Idaho Transportation Department’s District 3 boundaries, the highway covers 203 miles from Pinehurst in Adams County to the Oregon stateline south of Marsing in Owyhee County. Recreational travelers and local traffic share the road with long-haul trucks, straining the roadway capacity as surface transportation demand continues to grow.

The completed corridor plan will include an analysis of the existing conditions on the highway; a forecast of future demand over the next 20 years; and a list of short and long-term improvements on how to improve transportation on this section of U.S. 95. The document will address the course of the highway as a whole and on a county by county basis. The plan will be based on community input, engineering analysis, and city, county and agency visions for the future. ITD will include the plan in its Idaho Horizons Long Range Capital Improvement and Preservation Program (LRCIP). LRCIP is a planning document that helps ITD prioritize projects for future years.

The finished corridor plan will address:

• Safety: What are the improvements that will make U.S. 95 safer for motorists, pedestrians and residents?
• Access Management: How can ITD and local communities manage the effect of development along the corridor so the roadway continues to function safely and efficiently?
• Traffic: Can we anticipate congestion points and plan for the best ways to improve traffic flow and capacity throughout the corridor?
• Environment: What are the important environmental issues to consider when ITD seeks to make improvement to U.S. 95 in the future?

The U.S. 95 Corridor Study began in 2007 and is expected to be completed in 2016.

Project Background
The Snake River Bridge in Marsing was constructed in 1951 and is the primary river crossing for the area. The bridge has reached the end of its design life and needs to be replaced. ITD has evaluated options for rehabilitating the bridge and determined it is in the best interest of the community to remove and replace the bridge.

This project includes an environmental evaluation. The evaluation accounts for factors such as Snake River physa snail habitat, the nearby Marsing Island Park and the needs of agricultural traffic and boaters.

• August 2015 Open House Summary

About the Idaho 16 corridor

• The long-term vision of this corridor is to create an expressway for North/South travel in the Treasure Valley.
• Expanding this corridor is one of 33 unfunded projects in the Treasure Valley, as identified in the Communities in Motion long-range plan conducted by the Community Planning Association of Southwest Idaho (COMPASS) in conjunction with ITD.

What’s been done

• In 2014 ITD constructed the first leg of the corridor expansion, building a river crossing from Idaho 44 (State St.) to US-20/26 (Chinden Blvd.)
• ITD completed environmental study on the corridor in 2011. This determined the scope of the project and impacts to the area.
• ID-16 Corridor Map

What’s next

• Additional phases of this project are not funded at this time. After the preliminary engineering, ITD will be poised to quickly utilize funding to finish designs, buy property (right of way), and construct the project, should it become available.

Old Highway 30 Bridge History

The Old Highway 30 Bridge, designed by Caldwell City Engineer F. H. McConnel was built in 1922 by the American Bridge Company, which was a subsidiary of United States Steel, who also built famous structures like the Woolworth Building, the Chrysler Building, the Empire State Building, the Sears Tower and the San Francisco Bay Bridge.

At that time the bridge was called the Boise River and Canal Bridge, and at construction was part of the Idaho Pacific Highway that later became U. S. Highway 30. It continued to be called U. S. Highway 30 until the early 1960s when the nearby Interstate was constructed and the southeast portion of the roadway was renamed Plymouth Street, while the northwest side was renamed Old Highway 30.

The bridge allows access across the river and canals. It spans 388 feet across the Boise River and consists of a three-span through-truss. The bridge is beyond its functional lifespan and needs to be replaced. The existing structure is proposed to be converted into a pedestrian pathway as part of Caldwell’s Boise River Greenbelt.

Why Does the Bridge Need to be Replaced?

The Old Highway 30/W. Plymouth Street Bridge is located off Interstate 84 Exit 26 in Caldwell Idaho. The existing one-lane bridge crosses the Boise River, provides local access to the river, and surrounding neighborhoods. It is also a link between Caldwell and the Middleton area. This route has been used as a bypass to Interstate 84.

The current steel truss bridge is a three-span, 388-foot long structure constructed in 1922 and carries 1,350 vehicles a day, including buses and trucks. The existing bridge needs to be replaced due to its narrow width and poor, aging condition.

The general work will bring about a new bridge structure, bridge approach roadway, pathway relocation, and rehabilitation/retrofit of the existing bridge for pedestrian use. The improvements will provide a safe route for vehicles, bicycles and pedestrians.

What Will Happen to the Old Bridge?

It is planned to convert the existing bridge into a bicycle and pedestrian pathway. Proposed improvements include a new concrete deck and pedestrian railing. This approach will also allow separation of pedestrian/bicycle traffic from vehicular traffic providing for a safer pathway system.

Community Involvement

Canyon Highway District 4 and the City of Caldwell will use multiple communication tools and innovative technologies to gather public input and assess concerns of the local community. Future opportunities for community involvement include:

• Input Interviews – for example, City of Caldwell, Irrigation Districts, Flood Control Districts, Idaho Rivers United, etc.
• Web and Social Media Support
• Project Update Newsletters
• Open House Public Involvement Meetings

There will be two Open House Public Meetings in the summer of 2016 to introduce the project to the public and gain valuable information from the residents in the area. These meetings will be announced by a public meeting postcard as well as advertisements and notifications in the Idaho Press Tribune and other media outlets frequented by the community.
