Improve expand drainage and approach-roadway exit entry transitions to bridge. Construct a pedestrian bicycle walkway on the north side of the new bridge, connecting to existing paths on either side. Mitigate environmental impacts from construction to protect the Tolliver River.

Company Background

XJM Engineering Ltd. has forty years of experience in civil engineering projects ranging from building major highway interchanges to constructing double-decker bridges. See our website for catalog of the projects we have achieved. 85% of our projects come from repeat customers.

Benefits

The current bridge was constructed in 1962. It is obsolete and has been declared at risk of failure due to heavy use well beyond its original projected lifespan of fifty years. The new bridge will expand the current route from two lanes to four, increasing traffic capacity and safety for vehicles, and will add a safe, separate path for bicyclists and pedestrians, encouraging more commuting by bicycle and walking within our city.

Milestones

Management

XJM Engineering Ltd. will oversee the work of multiple contractors during the course of this three-year project.

Milestone Expected Dates

PKM Equipment Rentals Supplier of heavy equipment to be leased as needed. PennCo Asphalt Supplier of asphalt. Sureway Cement and Gravel Supplier of cement and gravel products.

Variety of state inspectors Inspectors from various departments will be needed to approve work so we can pass from one stage to the next.

Risk Backup Plan

Work slowdown or stoppage due to extreme weather such as thunderstorms, flooding, and blizzards Unfortunately, the weather cannot be controlled, but if it happens, we will work more hours to make up as best we can for lost time. Work slowdown or stoppage due to lack of vital materials such as cement and steel We have experienced problems in the past due to worldwide shortages of certain materials. When we can, we will purchase materials well in advance of need and identify several suppliers instead of only one.

Stoppage due to major accident on site. XJM Engineering Ltd. has a stellar safety record and will insist that subcontractors meet our standards in all areas to protect workers and equipment. The Tolliver Bridge lies in a rural section of PA-160, a state highway. The highway is four lanes wide in this section but must narrow to two lanes to pass over the old two-lane bridge.

The load limit of the bridge makes it unsafe for large trucks, and pedestrians and bike riders must share the traffic lanes with vehicles. This Impact Statement deals with transportation impacts. For environmental impacts on the Franklin River, see the Environmental page.

Description of Impact

The replacement of the Tolliver Bridge will necessitate a detour from PA-160 through the nearby town of Johnstown for a period of approximately 30 months. This may cause considerable congestion in and around that city, but the project is necessary to update the state highway and prepare for the future.

Methods for Determination of Impact

As this is a rural bridge, the only method we used to determine impact was to calculate daily traffic over the existing bridge. To do this, traffic counter strips were laid across the road at the eastern side of the bridge and attached to recording boxes, Traffic was counted for two months, July 20XX, which is considered the highest for vehicular traffic, and October 20XX, which is considered a low-travel month. The average daily vehicle traffic was 971, making a monthly average of approximately 29,616 vehicles per month or 355,386 per year.

It should be noted that of these vehicles, approximately 40% are commercial trucks weighing two tons or more. In comparison, traffic was counted on the Main Street of Johnstown during the same months. Average daily traffic there was 699 vehicles, which were 80% passenger cars and trucks, 20% commercial vehicles weighing two tons or more.

Impact Comparison

As this bridge is in a rural section of Pennsylvania on a modestly used highway, the impact to the state as a whole can be judged to be minimal. However, the city of Johnstown may find the impact of increased traffic, especially large trucks, to be quite substantial.

Remediation of Impact

There is no remedy for re-routing traffic during the bridge replacement project. However, the traffic from PA-160 need not be routed down Main Street in Johnstown. Instead, we should consider routing it down in a bypass down Oak Leaf Road, Bender Lane, and Road 122, all rural routes. This would impact far fewer people and commercial properties.

Next Steps

Some local merchants in Johnstown have expressed an interest in keeping the detour route through the heart of their city, in hopes that drivers and passengers may choose to stop and shop or eat in restaurants there. The final detour route must still be determined. To prepare the site for removal of the old bridge and installation of the new span, the following steps must be taken.

Removal of utilities from current bridge site. Electric cables and water lines are connected to the old bridge and must be removed with service remaining intact for customers. Current bridge span removed. An additional temporary access road will need to be constructed to allow removal of bridge sections.

Removal of trees and rocks from banks to prepare ground surface for new bridge. With two more lanes and a separate pedestrian bike path, the new bridge is thirty feet wider than the old bridge. Preparation of wider highway lanes and two access routes to new bridge.

PA-160 narrows from four lanes to two approximately 300 feet on either side of the bridge. The existing four lanes must now be extended to join up with the new four-lane bridge. This will necessitate some earth moving and removal of vegetation.

Preparation for pedestrian bike path to bridge. On the north side of the bridge, a new pedestrian bike path must be cleared to connect to the existing path along PA-160. Like many areas of the United States, the infrastructure in Pennsylvania, especially in rural areas, is in desperate need of repair and updating.

Our bridges and roads are in particularly bad shape. We hope the Tolliver Bridge will be the first of many bridges to be replaced with new infrastructure investment. The list of the top four most badly needed bridge replacements, in order of need due to deterioration, is.

Tolliver Bridge

Located in rural Cambria County and the subject of this proposal. Tolliver Bridge forces a narrowing of a state highway and is unsafe for pedestrians, bicyclists, and trucks with heavy loads.

Bridge 672

Located on Pennsylvania Route 3. Supports for this bridge do not allow for higher trucks to pass through, and entire bridge structure has been damaged by blows from passing trucks and ships.

Pitt Bridge

Located on US 19. Bridge supports are crumbling and may fail in the near future.

Bridge 43

Located on PA-171. Several support beams are severely rusted and may break soon. This is only a partial list of bridges that should be replaced.

Roads and utilities need attention, too. We urge the state of Pennsylvania to make maximum use of the current federal programs for infrastructure improvement. The following is our projected schedule.

If weather impacts any portion of this schedule, XJM Engineering Ltd. will add personnel and work hours to make up for lost time as best we can. The effect of this bridge replacement project on the Franklin River and surrounding environment is of key concern. XJM Engineering Ltd. is committed to minimizing the environmental impact. The Franklin River is known for trout fishing, including species of rainbow, brown, brook, and palomino trout.

Other fish species are there as well. Walleye, saugers, small and largemouth bass, along with spotted bass. Special care must be utilized to preserve the fish habitat and natural surroundings of the river banks, and to preserve a constant water flow within the river. This will necessitate skillful placement of rock barriers along the river banks and careful earth moving operations.

Runoff from the asphalt roadway will be directed into drainpipes and gravel-lined ditches to minimize chemical contamination of the river and surrounding area. XJM Engineering Ltd. has consulted with the Pennsylvania Fish and Boat Commission, the Pennsylvania Game Commission, and the Pennsylvania Department of Environmental Protection to develop plans to protect fish and other wildlife in the river area. Our work on this project will be continuously monitored by these authorities.

XJM Engineering Ltd. has developed the following budget for the Tolliver Bridge Replacement Project. Monies to be distributed to XJM Engineering Ltd. in monthly installments. Pennsylvania’s infrastructure and Approve final plans for bridge ensure a positive future replacement.

We can begin work after receiving final written approval from the state. Make first installment payment per contract. When funds have been deposited in XJM Engineering Ltd.’s account, we will begin all necessary purchases and work efforts for the project.

Inform and educate public about this project. The state of Pennsylvania and especially residents of the local project area must be kept informed about detours and other possible disruptions during the course of the project. This information should be posted on the state’s transportation websites and other sites as well.

Together we will rebuild Pennsylvania’s infrastructure and ensure a positive future for a growing population. XJM Engineering Ltd. looks forward to working with the state on this project and we guarantee your satisfaction in all phases of this project.
