Process for Invoicing and Reimbursement
This process allows the Department to invoice and receive payment for a sign installation from an outside party. Signs covered under the following must be unplanned sign installations. They must be in the same fiscal year, they cannot carry over. 1. Prepare the estimate for fabrication and installation (all costs, including fringes, shipping, etc.). Do not fabricate or install the sign at this point. Also, do not accept payment from the outside party. 2. Send to Region financial analyst. They will work with Finance to create an invoice. Financial analyst, please refer to Guidance Document 10153. A memo with a completed TWA form (form 1515) is sufficient. Finance will invoice the party requesting the sign. 3. When the payment is received by Finance they will add the money to the coding that you provided them with on the TWA form (probably region maintenance coding). 4. Once you are contacted by Region Finance, you may fabricate and install the sign and charge to the same coding that was originally submitted. Do not fabricate or install before the funds are added to the designated account.

with any other sign except STOP and YIELD, providing the amount of legend does not interfere with a clear understanding of all signs in the same installation. [The River Name (I3-1) sign can often be combined with the Object Marker (OM-3) sign.]
76. FREEWAY – Freeway signs should not be combined except where the signs are
designed to supplement each other. 77. CONSTRUCTION – The combining of signs in construction areas should follow the
same general guidelines as set forth for signs previously described 78. SCHOOL – (S1-1) – For advance warning, shall use W16-2, 2a, or 9p. At crossing shall
use W16-7p. 79. SCHOOL SPEED (R2-1 and S4) – None, except as specified in Part 7 of the MMUTCD 80. R.R. CROSSING (R15-1, 2) – None except as specified in Part 8 and 10 of the
MMUTCD 81. R.R. ADVANCE WARNING (W10-1) – R4-1 (if appropriate), W10-1a (if appropriate),
parking control signs, and W16-10 (if appropriate). 82. DO NOT STOP ON TRACKS (R8-8) – None 83. BICYCLE SIGNS – The same general principles of sign combinations as outlined for
motor vehicle operators can be applied to signing for bicyclists.

APPENDIX C
Arrow Per Lane
Appendix C SUBJECT: Multi-Lane Exits with an Option Lane PURPOSE: To Promote Uniform Application of Guide Signs at Multi-
Lane Exits COORDINATING UNIT: Traffic Signing Unit INFORMATION: The following is only for multi-lane exits with an option lane. Overhead arrow-per-lane signs are to be used with all major interchanges with other expressways or freeways, high-volume multi-lane highways, principal urban arterials, or major rural routes where the volume of interchanging traffic is heavy or includes many road users unfamiliar with the area. (Cases 1-4) Multiple exit destinations will show both destinations but will not be split by destination until the 0.5 mile location. (Case 5) Do not use an overhead arrow-per-lane guide sign at the gore point if the service life on the truss located at the gore is such that it does not need to be replaced. Use a pull through guide sign and an exit direction guide sign on the existing truss instead. (Case 6) For smaller intermediate or minor interchanges, traditional signing practices should be used. (Cases 7-8) Use exit only plaques for arrow-per-lane signs at the ½ mile location and divergence point. For Freeway splits when no exit number is used, omit the exit only warning plaques completely. The panel I sign design should be used in all cases. Panel II is only to be used when the field conditions do not allow for the panel I sign. (Case 9)

APPENDIX D
Roundabout Signing Guidelines
Appendix D
SUBJECT: Roundabout Signing Guidelines
PURPOSE: To Promote Uniform Application of Signs at Roundabouts
COORDINATING UNIT: Traffic Signing Unit
INFORMATION: The following describes the signing used at example roundabouts, and provides information about each sign in regards to when and where each sign can be used.
This document was formed using elements from the NCHRP Report 672 Roundabouts: An Informational Guide, the FHWA Roundabout Guide Chapter 7.1, and the 2011 Michigan Manual for Uniform Traffic Control Devices (MMUTCD).
Sizes of these signs shall match the required size per the 2011 MMUTCD and the current version of the Traffic Sign Design, Placement, and Application Guidelines (TSDPAG). Sign supports shall follow the standard sign support details in the TSDPAG. Any roundabout sign shall not combine any elements outside of their classification (i.e.: green and white guide signs shall not contain warning sign elements).
The following paragraphs describe each sign. All referenced figures refer to the figures within this document.
Signs on Roundabout Approaches:
- W2-6 (Circular Intersection Sign) – This sign shall be required to be the first sign on the approach of a roundabout. The sign shall be clustered with the “Roundabout” plaque (W16-17P) and the appropriate advisory speed (W13-1). Figure 1 provides an example for these signs.
o For tear-drop roundabouts, the W2-6 sign shall be replaced with a W6-1 sign, and the W16-17P shall be eliminated.
- A guide sign shall be required to be the second sign on the approach of a roundabout. This sign will give destination information so the driver can decide what turn movement is required. The D1-2d series and the D1-3d series shall be used to provide the driver direction on what direction to turn. Freeway off-ramp applications shall use the D1-5 sign or some variation of it (see Figure 2 for non-freeway examples, see Figure 11 for freeway off-ramp example).
- A regulatory lane-control sign shall be the third sign on the approach of a roundabout if multiple approach lanes continue into the roundabout. If the roundabout has a single lane approach, a lane-control sign shall not be used. Sign details R3-7g and R3-7h are examples of the lane-control signs (see Figure 3).
- Route Marker Clusters – These signs should be used in advance of the roundabout after the W2-6, Guide Sign, and (if any exists) lane control sign (see Figure 4).
D-2
- R4-7 (Keep Right Sign) – This sign shall be placed at the nose of the splitter island on each approach to the roundabout (see Figure 5).
- W3-2 (Yield Ahead Sign) – These signs shall not be used in normal circumstances. The W3-2 shall only be used when the sight distance of the yield sign is severely limited.
- Movement prohibition signs (R3-1, 2, 3, and 4) are prohibited within and approaching roundabouts.
- R2-1 (Yield Sign) – All roundabouts shall be required to have a yield sign placed on both the left and right hand side of the entry into a roundabout (see Figure 6).
- W11-2 (Pedestrian Crossing Signs) – Pedestrian crossing signs are only required on roundabouts with established pedestrian crossings. For all roundabout approaches with pedestrian crossings, the W11-2 shall be placed on the right-hand side of the road, placed just beyond the pedestrian crossing. For roundabouts with multiple approach lanes and pedestrian crossings, a W11-2 shall be placed on both the left-hand side and the right-hand side of the roadway just beyond the pedestrian crossing.
o If used, the W11-2 shall be combined with the diagonal arrow plaque, W16-7P (L or R) (see Figure 7).
Signs within Roundabouts:
- R6-4a, 4b (Roundabout Directional Arrow Sign(s)) – The central island of a roundabout shall have one roundabout directional arrow sign per approach. These signs shall be placed in the central island of the roundabout in target position of the approach lanes and shall be mounted with 4’ bottom height. The R6-4a sign shall be used on single lane roundabouts and the R6-4b shall be used on roundabouts with multi-lane approaches (see Figure 8).
- Street name “exit” signs shall be placed in the splitter island at the exit of a roundabout. These signs shall be one of five options (see Figure 9):
I) Route marker cluster with M6-2 as the arrow II) D1-1d (1.1) – Legend only III) D1-1d (1.2) – Legend only IV) D1-1d (1.3) – Legend and route marker in the same sign
a. *only to be used at roundabouts at junctions* V) Nothing
Signs leaving Roundabouts:
- After exiting a roundabout on a state trunkline highway, a confirmatory route marker cluster shall be erected within 200’ from the edge of circulating traffic.
D-3
o If the roundabout lies at a junction of two state trunklines, typical junction signing shall be followed (Route, Speed, Distance). Speed and distance signs are optional if the roundabout is not at a junction.
- W11-2 (Pedestrian Crossing Sign) – Roundabout exits with an established pedestrian crossing shall have a W11-2 sign placed on the right-hand side of the road just beyond the pedestrian crossing. If there are multiple lanes exiting from the roundabout with an established pedestrian crossing, the W11-2 sign shall be placed on both the left-hand and right-hand side of the road just beyond the pedestrian crossing.
o If used, the W11-2 shall be combined with the diagonal arrow plaque, W16-7P (L or R).
- W4-2R (Lane Ends Sign) - If lanes exiting a roundabout merge, a lane ends sign shall be placed at the beginning of the lane taper (see Figure 10).
o If pedestrian signs are used at the multiple lane exit of the roundabout and sign spacing is insufficient to place a W4-2R, the signs shall be spaced so that the pedestrian signs are placed in the required spot (at the ped x-ing) and the W4-2R will be placed as far back as possible to be seen after the pedestrian sign, or at the start of the lane taper.
Signs on Freeway Off-Ramps:
- All previous signing principles shall be followed for roundabouts at freeway interchanges. The freeway off-ramps shall be treated as a roundabout approach.
- Overhead signing may be used for roundabouts on freeway off-ramps or for locations with special circumstances. Span wires, trusses, and cantilevers may be used.
o All other signing options shall be considered prior to placing signs overhead. Overhead signing shall be avoided if possible.
o Only guide sign information (D1-5) or regulatory lane-control signs (R3-5d Series) (see Figures 11 and 12) may be placed on overhead structures, but they shall not be placed on the same structure.
Signs for Right-Turn Bypass Lanes:
- The roundabout approach shall contain the circular intersection cluster (see Figure 1) and a guide sign (see Figures 2 and 11).
- The regulatory lane-control sign shall be incorporate a normal right turn only arrow while maintaining the appropriate roundabout arrows for the other lane(s). Sign details R3-7g Mod and R3-7h Mod are examples of the lane-control signs (see Figure 13).
- The route marker cluster should be used in advance of the bypass lane after the W2-6, Guide Sign, and lane control sign.
D-4
- W12-1 (Double Arrow Sign) – Shall be placed at the nose of the splitter island splitting the bypass lane from the through lanes (see Figure 14).
- W11-2 (Pedestrian Crossing Sign) – Roundabout bypass lanes with an established pedestrian crossing shall have a W11-2 sign placed on the right-hand side of the road just beyond the pedestrian crossing. If there are multiple bypass lanes exiting from the roundabout with an established pedestrian crossing, the W11-2 sign shall be placed on both the left-hand and right-hand side of the road just beyond the pedestrian crossing.
o If used, the W11-2 shall be combined with the diagonal arrow plaque, W16-7P (L or R).
- W4-1 (Merge Sign) – The merge sign shall be placed at the far end of the splitter island where the bypass lane merges with the exiting lane (see Figure 15).
- W4-2R (Lane Ends Sign) – The lane ends sign shall be placed at the beginning of the lane taper where the bypass lane merges with the exiting lane.
The signs shown in Figures 16 through 20 at the end of this document show the preferred sign layout for the entrance, interior, and exit of a roundabout, roundabouts on freeway off-ramps, and roundabouts with a right-turn bypass lane. The signs in these figures shall be present at all times when signing a roundabout except as designed in the preceding paragraphs. As in any case, engineering judgment can be applied to deviate from these guidelines. Due to the number of signs for roundabouts, proper sign spacing is not achievable. For this reason, sign spacing may be reduced to a minimum of 150’ (for roundabout signing only).
