SECTION 5

Lane Closures / Width Restriction Considerations Notes

Page 5 of 9FORM 735-9983 (4-19) Mobility Considerations Checklist

1. If lane closures are planned, indicate which lanes will be closed, whether the work zone is on a curve or straight section, and how much paved width will be available to traffic between barriers/traffic control devices (e.g. barrels, cones, candlesticks, equipment, concrete barriers, etc.). If the width* will vary depending on the stage/phase of the project, list the available width, mile point range, and duration of each stage/phase.

*Note: Width generally refers to the paved width of the lane and any shoulders which are capable of supporting the freight traffic loads without failure. On a case by case basis, unpaved/aggregate shoulders may be determined to be useable.

Traffic control will include two stages. Stage I will allow traffic in the eastbound travel lane(s) while work is completed in the westbound travel lane(s). Stage II will flip the work to the opposite lanes. The work zones at all locations are on tangent sections of OR58.

At MP 2.46, 12-feet will be provided between the face of barrier and the foot of the candlestick devices, with three-feet of clearance to the work zone. The short term night lane closures are expected to occur for approximately 40 nights. The traffic flow will be controlled by flagging operations with typical tapers approaching/ departing the bridge as shown in the TCP.

At MP 33.24,12-feet will be provided between the face of barrier and the foot of the candlestick devices, with four-feet of clearance to the work zone. The short term night lane closures are expected to occur for approximately 20 nights. During the bridge deck overlay approximately 12-feet will be provided between the face of barrier and the foot of the channelizing candlestick devices. The bridge deck overlay is expected to be complete in approximately 4 nights. The traffic flow will be controlled by flagging operations with typical tapers approaching/departing the bridge as shown in the TCP.

At MP 35.98 two travel lanes and one shoulder will be closed at night providing two 12-foot lanes with shoulders (a minimum of 28' clear width) between the edge of barrier and the candlestick devices for pedestrian and bicycle traffic. Typical lane closure and shifting tapers approaching and departing the bridge will be in place as shown in the TCP. No flagging operations are anticipated.

The joint seal repairs are expected to take approximately 10 nights total.

At MP 38.25, 12-feet will be provided between the face of barrier and the foot of the candlestick devices, with four-feet of clearance to the work zone. The short term night lane closures are expected to occur for approximately 20 nights. During the bridge deck overlay approximately 12-feet will be provided between the face of barrier and the foot of the channelizing candlestick devices. The bridge deck overlay is expected to be complete in approximately 4 nights. The traffic flow will be controlled by flagging operations with typical tapers approaching/departing the bridge as shown in the TCP.

2. Will there be lane closures under structures? If so, is there an “up and over” diversion available?

No.

3. Have travel lane widths been reduced? If so, what are the lane widths?

No.

4. Will there be less than 28-feet for two lanes of one-way traffic, or for two opposing lanes of head-to-head traffic? If so, how much width will you have and describe the traffic control method. (Provide staging plans if available).

Yes. One 12-foot travel lane will be provided allowing two-way traffic in a single lane under flagging operations at MP 2.46, MP 33.24, and MP 38.25.

At MP 35.98, a minimum roadway width of 28 feet will be provided for two opposing lanes with shoulders.

Page 6 of 9FORM 735-9983 (4-19) Mobility Considerations Checklist

5. Does the available horizontal width between traffic control devices restrict annual permits? Contact the MCTD Mobility Team for help determining.

Yes, the horizontal width restricts annual permits.

6. Can all unannounced (no advanced notice required) oversize loads be accommodated safely through the restricted work zone by moving equipment and traffic control devices out of the way and waving them through with a slight delay (e.g. less than 20 minutes)? Indicate how long the anticipated delay will be. Will the travelling public also be delayed as a result?

No.

According to the Freight Mobility Nighttime Width Map (www.oregon.gov/odot/ProjectDel/Mobility/ NighttimeWidthMap.pdf), OR58 is a green route. As such, loads with annual permits and oversize loads traveling through OR58 at night are restricted by a 10’ width restriction. 10’ wide loads can be accommodated at night at all four bridge sites. Oversize loads greater than 10’ wide would have to go through the CCD restriction notice process if they want to travel through OR58 at night.

Oversize loads greater than 10’ wide can be accommodated through the project area since there are no planned lane restrictions during the daytime.

7. If unannounced loads cannot be accommodated, can loads with advance notice be accommodated on a case by case basis? If yes, how much advance notice will be required? If the answer is no, provide the oversize load detour route per Q.3 under Section 7 (Detour Route Considerations).

N/A

SECTION 6

Ramp Width Restriction or Closure Considerations Notes

1. If ramp closures are planned, list the ramps by name, number, and whether they are “on” or “off” ramps.

No ramp closures planned.

2. How long will each ramp be closed? Indicate hours and days needed for each.

No ramp closures planned.

3. Will any ramps be width restricted? If so, how much paved width will be available to traffic between barriers/traffic control devices? What are the days/hours of the width restriction?

No ramp closures planned.

SECTION 7

Detour Route Considerations Notes

1. For “road-closures” what is the approved detour route? No road closures are planned.

2. Will the detour route accommodate the same sized vehicles (annual permitted dimensions and/or single-trip permitted dimensions), that are normally allowed on the proposed route that is going to be restricted?

Contact the MCTD Mobility Team for help determining.

No detour routes needed.

3. If the detour route cannot accommodate the same size vehicles as the proposed restricted route, has an additional detour route been identified? If so, please describe.

No detour routes needed.

4. Has the detour route been checked for overhead obstructions to ensure all vehicles can travel the entire route? (E.g. structures, wires, signal heads, overhanging trees, etc.)

No detour routes needed.

5. Has the detour route been checked for weight restrictions over structures? Contact the MCTD Mobility Team for help.

No detour routes needed.

6. Have turning movements been evaluated to see if they provide safe turning movements and off tracking? Contact the MCTD Mobility Team to obtain oversize load information, including truck diagrams.

No detour routes needed.

Page 7 of 9FORM 735-9983 (4-19) Mobility Considerations Checklist

7. If the detour route uses city streets/county roads, has it been approved by the local jurisdiction? List approver.

No detour routes needed.

8. The District road authority must approve detour routes when requested to allow increased oversize load dimensions to accommodate the vehicles routinely allowed on the restricted route. Contact the MCTD Mobility Team for help determining if approval will be needed.

No detour routes needed.

9. Will the detour route be signed? No detour routes needed.

10. For “ramp-closures”, what are the detour routes? If using the next exit, how will this be communicated to drivers?

No ramp closures will be needed, no detour routes needed.

11. If routed to the next exit and instructed to reverse direction, has the highway undercrossing been evaluated for height?

NA.

SECTION 8

Special Detour Route Considerations Notes

1. How will the detour route affect emergency services response times? No detour routes needed.

2. Will vehicles transporting hazardous materials be able to use the planned detour route?

No detour routes needed.

3. Are there other projects along the proposed detour route which will restrict traffic?

No.

SECTION 9

Critical Route Pair Considerations Notes

1. Is the project on a critical route pair? See Mobility Procedures Manual for help.

Yes. OR58 is a critical route pair with OR126 (McKenzie Highway, No. 15).

2. If the project is on a critical route pair, is work taking place on the paired route that also has restrictions, and/or delays that exceed allowable thresholds? If yes, name the project and describe restrictions and/or delays.

OR126 has a paving project slated for April - August 2023.

The project name is: "OR126: Greenwood Drive - Vida (K21543)". It is located at MP 21.65 - 26.58. It will restrict lane closures to occur only at night.

3. If there are no conflicts identified, who confirmed this information? (E.g.

the Transportation Project Manager or Mobility Liaison? Traffic Engineer?)

Do not anticipate conflicts or issues with closing a lane on OR126 at night as traffic volumes are much lower at night than during the day. Region 2 Resident Engineer confirmed this information.

SECTION 10

Height, Length & Weight Considerations Notes

1. If your project has bridge work that has load rating factors showing insufficient load capacity for unrestricted use by Permit Vehicles, ODOT's Weight Restrictions Policy (PMT 06-01) must be followed. If your work will require restricting the bridge, please describe the restriction (annual, single trip) per the Bridge Unit. Weight restrictions will be posted on the Road and Bridge Restriction list.

N/A.

2. When projects have work zones that have a high degree of curvature (more than 5 degrees) the overall length of oversize loads may need to be restricted. Is a length restriction necessary? If so, please describe.

No.

3. Are there any traffic control devices or construction tools in the work zone that temporarily reduce the overall height available to loads?

(E.g. temporary signals, falsework, containment systems, etc.)

No.
