Project Background

The Karcher Interchange opened to traffic in 2006. The interchange provides a link to I-84 for commuters in southern Canyon County and provides access to SH-55 (Karcher Road).

Midland Boulevard, which has direct access to I-84 at the Karcher Interchange, is an important north-south roadway. Development along Midland Boulevard has stimulated significant increases in traffic in the past several years. In 2015, it was estimated that over 15,000 vehicles per day used Midland Boulevard between I-84 and Cherry Lane. The regional traffic model forecasts traffic could double by the year 2040.

Project Description
The City of Nampa and the Idaho Transportation Department (ITD) are partnering to study the I-84 Karcher Interchange in Nampa, Idaho. The study will determine options to improve safety and accommodate traffic through 2040.

Completion of the study will allow the City of Nampa and ITD to plan improvements as funding becomes 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.

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

Those with questions about the corridor study can send an e-mail to adam.rush@itd.idaho.gov or call Adam Rush at (208) 334-8119.

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.
