1 PUBLIC OFFICIALS MEETING MAY 11, 2016 AGENDA I. INTRODUCTIONS V. CURRENT PROJECT STATUS VI. PROJECT SCHEDULE VII. UPCOMING ACTIVITIES VOPEN DISCUSSION & QUESTIONS IX. ACTION ITEMS 1

2 A. Bridge Lighting Cost Responsibility Action Item - District will look into PennDOT policy for free and limited access to determine why bridge lighting is not a shared cost Resolution PennDOT policy does not specify bridge lighting energization and maintenance costs to be shared (by PennDOT and the local government) because bridge lighting primarily serves an aesthetic purpose B. Emergency Crossovers Action Item - The design team will look into the feasibility of another emergency crossover between the Selinsgrove and PA 61 Connector Interchanges Resolution There are two additional feasible locations. PennDOT proposes constructing three emergency crossovers within entire Southern Section. B. Emergency Crossovers Additional Recommended Feasible Crossover Locations Original Recommended Crossover Locations C. Emergency Crossover Indicators Action Item - The District will investigate if signing or other indicators (reflectors) can be used to help accentuate emergency crossovers in inclement weather Resolution The District has recently added fluorescent orange plaques to existing signage at emergency crossovers on its freeways 2

3 D. Mile Markers Action Item - The project team will check policy to determine if mile markers will be allowed on the CSVT roadway. Resolution Mile markers can be provided. The beginning/ending points and numbering convention will be determined as final design continues. E. Minimizing Delay on North-South Roadways in Monroe Township Action Item - There are a limited number of roads that go North/South through Monroe Township. The project team will look into minimizing delays due to construction along the North/South routes in Monroe Township Resolution We will continue to look at this as the traffic control plan is developed Value Engineering report recommends studying the elimination of the CSVT bridges over Attig Road and Grangers Road What is your opinion? E. Minimizing Delay on North-South Roadways in Monroe Township E. Minimizing Delay on North-South Roadways in Monroe Township CSVT Structure over Attig Road: $3.2 Million Construction Cost 0.7 Miles ~ 1 Minute Current ADT (2016): 738 Vehicles 1.6 Miles ~ 3 Minutes CSVT MONROE CREEK CSVT Structure over Grangers Road: $6.3 Million Construction Cost 0.3 Miles ~ 1 Minute Current ADT (2016): 268 Vehicles 2.2 Miles ~ 4 Minutes F. Mill Road and Airport Road Intersection Action Item - The design team will study the proposed intersections at Mill Road / Airport Road and Mill Road/ App Road to make sure they work effectively for current and future traffic volumes. Colonial Acres Resolution - This will be addressed later in the presentation in Item IV.B. Mill Road / Airport Road / App Road Cortland Drive US 11/15 Split US 522 Interchange PA 61 Connector Interchange 3

4 A. US 522 Interchange Preliminary Design EXISTING ROADWAY REMOVAL PROPOSED ROADWAY PROPOSED SHOULDER BRIDGE WORK PROPOSED STRUCTURE CUT LINES FILL LINES A. US 522 Interchange - Why evaluate this area? Review the proposed geometry based on current design criteria Investigate roundabouts for the On- and Off-Ramp intersections with US 11/15 and US 522 Evaluate feasibility of a left turn lane from existing northbound Off- Ramp to US 522 southbound Conduct analysis of the merge/diverge areas on existing US 11/15 and US 522 A. US 522 Interchange Changes Made Updated alignments to current design criteria: Modified northbound On-Ramp (Ramp B) Improved radius for northbound On-Ramp (Ramp C) Modified existing northbound Off-Ramp (Ramp G) A. US 522 Interchange Current Design Ramp C Alignment A. US 522 Interchange Benefits & Impacts Benefits Eliminates proposed widening of existing bridge over US 522 Complies with current design criteria Reduces likelihood of truck roll-overs on existing northbound Off-Ramp (Ramp G) Impacts Additional right-of-way from C. Ronald and Linda Stuck Parcel Ramp G Alignment Ramp B Alignment 4

5 A. US 522 Interchange Additional Studies Roundabout analysis determined that operations would fail. Left turn lane is not desirable for northbound Off-Ramp due to proximity of adjacent signals. Existing jug handle will remain to accommodate this movement Additional analysis is currently being conducted for merge/diverge areas on existing US 11/15 and US 522. A. US 522 Interchange Additional Studies Ramp D signal operation and Jefferson Avenue: Optimal signal operation along US 522 requires Jefferson Avenue access to be eliminated Jefferson Avenue access still provided via Airport Avenue, Washington Avenue and Old Trail. Airport Road jug handle: Airport Road jug handle would be eliminated Left turn phase provided for US 522 southbound onto Airport Road at existing signal A. US 522 Interchange Additional Studies B. Mill Road/Airport Road/App Road Preliminary Design Remove jug handle Eliminate Access OLD TRAIL B. Mill Road/Airport Road/ App Road Why evaluate this area? Improve the skew between Mill Road and the CSVT bridge Eliminate the impact to Aqua chlorine tank facilities along Airport Road Improve the intersection operation for Mill Road & Airport Road/App Road B. Mill Road/Airport Road/ App Road Changes Made Realigned Mill Road Realigned Airport Road Replaced T intersections with roundabouts 5

6 B. Mill Road/Airport Road/ App Road Current Design B. Mill Road/Airport Road/ App Road Benefits & Impacts Benefits: Removes skew between Mill Road and CSVT, reducing bridge size Avoids Aqua chlorine tanks Reduces the required right-of-way nearly 50% Improves sight distance Accommodates future growth Roundabouts Improves safety at the intersection (Crash rate is currently 3.5x higher than state average for similar intersections.) Savings of approximately $1 million B. Mill Road/Airport Road/ App Road Benefits & Impacts Impacts: Reduced travel speeds through the intersection (possible benefit) B. Mill Road/Airport Road/ App Road Why choose a roundabout? Safer operations with: Reduced speeds Reduction in number of turning conflicts Eliminated potential for right-angle, left-turn and head-on collisions National Cooperative Highway Research Program studies have shown roundabouts provide the following safety benefits: 35% reduction in all crashes 76% reduction in injuries 90% reduction in fatalities B. Mill Road/Airport Road/ App Road Why choose a roundabout? Improved operations and traffic flow between intersections for projected future traffic volumes DESIGN REFINEMENTS B. Mill Road/Airport Road/ App Road Roundabout Operations Roundabout Operation APP ROAD Accommodates all vehicle types including trucks, emergency vehicles and farm equipment 2044 Design Year Traffic Volumes (Vehicles per day): Mill Road: 9,668 Airport/App Road: 1,721 Pavement Removal 6

7 C. Colonial Acres Preliminary Design C. Colonial Acres Why evaluate this area? Constructability concerns with preliminary design Desire to optimize efficiency Fisher Road C. Colonial Acres Why evaluate this area? C. Colonial Acres Changes Made Eliminated bridges over Fisher Road Realigned Fisher Road from the north to form a T intersection with Park Road Terminated Fisher Road from the south with a cul-de-sac Park Road Colonial Drive Fisher Road Rolling Green Run Unnamed Trib Realigned Colonial Drive Placed stream (Channel 23) along Fisher Road in a culvert C. Colonial Acres Current Design C. Colonial Acres Benefits & Impacts Benefits Eliminates constructability issue of embankment between bridges Eliminates bridge over Fisher Road saving approximately $5 million in construction cost and future maintenance cost Cul-de-Sac Relocated Impacts Cul-de-sac on Fisher Road Additional wetland & stream impacts Bridges Eliminated Channel 23 Culvert Relocated 7

PA 61 Connector Changes Made D. PA 61 Connector Current Design Eliminated dual left turns from PA 61 northbound Off-Ramp to US 11/15 southbound (Ramp K) Added loop ramp (Ramp P) to accommodate PA 61 northbound to US 11/15 southbound traffic Shifted PA 61 to eliminate bridge replacement over US 11/15 Added Loop Ramp P Eliminated Bridge Replacement Eliminated Dual Left Turns D. PA 61 Connector Benefits Accommodates design year traffic volumes Preserves existing US 11/15 bridge substructure Shamokin Dam Interchange Impacts Requires larger bridge on PA 61 Connector over Ramps P and L Requires larger footprint Increases construction cost by approximately $1 million Reminder: New Signal 8
