CURRENT & RECENT PROJECTS
Pavement Rehabilitation Projects
All listed completion dates are tentative and subject to change
Willis Road
Old Highway 30 to Emmett Road
Project: This project consists of pavement removal, excavation, new gravel base, and a new asphalt mix pavement surface on a little more than 2 miles of roadway. Minor changes to vertical curves, grades, and road width are anticipated to provide greater safety and consistency throughout this road segment. Pipe replacements and extension, and ditch grading will occur to improve drainage. This road will be closed to thru traffic during construction with provided access. A large pipe at East Harley Gulch will be replaced ahead of the road construction and will require a road closure to all traffic as described under the Pipe Projects below.
Status: Complete
Lake Avenue
Lake Lowell Ave to Karcher Road (Hwy 55)
Project: Rehabilitation of the pavement in this 2 mile long project will be accomplished by pulverizing the existing asphalt pavement and leaving it in place to provide additional gravel base depth. The pulverized asphalt supplemented with additional crushed gravel will then be graded to provide a uniform roadway and improve the ride. This will be followed by construction of a 4" thick asphalt plant mix pavement surface. This road will be closed to thru traffic during construction with a detour. However, local traffic and services (mail, garbage, and emergency services) will be provided access.
Status: Complete
Ustick Road
Beet Road to Weitz Road
Project: Rehabilitation of the pavement in this 1.5 mile long project will be accomplished by pulverizing the existing failing asphalt pavement and leaving it in place to provide additional gravel base depth. A 1/4-mile section will require excavation and new gravel base. After grading the pulverized asphalt with additional crushed gravel as needed and minor grading to improve the ride, a 4" thick asphalt plant mix pavement surface will be constructed. This road will be closed to thru traffic during construction with a detour. However, local traffic and services (mail, garbage, and emergency services) will be provided access.
Status: Complete
Lake Avenue
Karcher Road (Hwy 55) to Homedale Road
Project: This 1 mile long project consists of pavement removal, excavation, new gravel base, and a new asphalt plant mix pavement surface. Pipe replacements and extension, and ditch grading will occur to improve drainage. This road will be closed to thru traffic during construction with a detour. However, local traffic and services (mail, garbage, and emergency services) will be provided access.
Status: Construction postponed to 2019
Lake Lowell Avenue
Lake Avenue to Midway Road
Project: This slightly less than 1 mile long project consists of several components. The easterly 1/4-mile will involve pavement removal, excavation, new gravel base, and a new asphalt plant mix pavement surface. The remainder of the project will have a 2" asphalt overlay and includes the replacement of aging guardrail with new guardrail. Minor pipe replacements and extension, and ditch grading will occur to improve drainage. This road will be closed to thru traffic during construction with a detour. However, local traffic and services (mail, garbage, and emergency services) will be provided access.
Status: Complete
Bridge Projects
Middleton Road
Bass Lane to Sawtooth Drive
Project: Middleton Road will be restricted to one lane of travel while an epoxy overlay is placed on the bridges over Boise River and Fifteen Mile Creek. The epoxy overlay will seal minor bridge deck cracking and provide a new wearing surface, extending the life of the structure and minimizing more extensive bridge deck repair work in the future. The one lane of traffic through the construction will be controlled with flaggers or temporary traffic signals. Motorists can expect traffic delays during the construction and are urged to use alternate routes.
Status: Complete
Pipe Projects
Weitz Road
At Dixie River Road
Project: This project involves replacement of a failing corrugated metal pipe arch under Weitz Road just north of Dixie River Road and includes grading the road to decrease the slope and add cover over the new pipe.
Status: Complete
Lincoln Road
Between Georgia Street and Mason Road
Project: This project involves replacement of a deteriorated 48" corrugated metal pipe under Lincoln Road approximately 1/4-mile east of Georgia Street with 42" reinforced concrete pipe. The pipe will be extended on the north side to provide a safer roadside. A concrete box on the south side will allow connection to an existing corrugated metal pipe from the west and a change in direction of the concrete pipe to align with the drain to the east, and eliminating a portion of the deep drain along the road. This road will be closed to traffic at the pipe crossing location during construction with a detour. Local traffic and services (mail, garbage, and emergency services) will be coordinated with for access.
Status: Complete
Willis Road
Between Freezeout Road and Emmett Road
Project: This project involves replacement of a deteriorated 36" corrugated metal pipe under Willis Road and the Canyon Hill canal approximately 1/4-mile west of Emmett Road with 60" HDPE pipe. Precast concrete headwalls will be constructed on each end and a new canal overflow structure will be included. This road will be closed to traffic at the pipe crossing location during construction with a detour. Local traffic and services (mail, garbage, and emergency services) will be coordinated with for access.
Status: Complete
CanAda Road
At Dixie River Road
Project: This project involves replacement of a failing corrugated metal pipe arch under CanAda Road approximately 1000' north of US 20/26 with a new coated corrugated metal pipe and a concrete box structure. This road will be closed to traffic at the pipe crossing locations during construction with a detour. Local traffic and services (mail, garbage, and emergency services) will be coordinated with for access.
Status: Complete
Midland Boulevard
Between Ustick Road and Linden Road
Project: This project involves replacement of a deteriorated 36" corrugated metal pipe with concrete extensions under Midland Road approximately 1/4-mile north of Ustick Road with 48" reinforced concrete pipe. The pipe will be extend on both sides to provide a safer roadside. This road will be closed to traffic at the pipe crossing location during construction with a detour. Local traffic and services (mail, garbage, and emergency services) will be coordinated with for access.
Status: Complete
Other Projects
Indiana Avenue & Homedale Road
Indiana & Homedale Roundabout
Project: This joint project between Canyon Highway District No. 4 and City of Caldwell consists of constructing a single lane roundabout at the intersection of Indiana Avenue and Homedale Road. The roundabout will be similar in size to the one constructed one-mile north at Indiana Avenue and Ustick Road. The project includes gravel base, asphalt paving, concrete work (curb, gutter, sidewalk, & truck apron), street lighting, storm drainage, irrigation relocation, signage and pavement markings, and other related work.
Status: This project is currently in preliminary design. Information can be viewed at the following links: Indiana & Homedale Roundabout Plan View, Indiana & Homedale Roundabout Handout
Completion Date: Construction is anticipated in summer 2019, depending on available funding.
Middleton Road & Linden Road
Intersection Improvements - Multi-Lane Roundabout
Project: CHD4 is planning improvements to the intersection of Middleton Road and Linden Road in Caldwell. The intersection, currently all-way stop controlled, is experiencing significant congestion during peak hour traffic, and also has a substantial crash history. Studies conducted in 2013 and 2016 compared alternatives for the intersection control, and determined that a multi-lane roundabout would provide the most efficient and safest solution at the intersection. CHD4 has prepared several concept designs to examine the impacts of these intersection improvements to existing residential property, the Caldwell Highline canal, and surrounding farmland. These concepts were presented to the public at an Open House May 9th, 2018 at Vision Charter School in Caldwell. Links to the exhibits on the Middleton Rd corridor, the intersection comparisons, and project concepts are included below for your reference.
Status: This project is currently in the concept design phase. Right-of-way acquisition is anticipated to begin in 2019, and construction is tentatively scheduled for 2021 depending on availability of funding. The project will be funded with local dollars.
