How to Build a Traffic Control Plan for Road Construction Projects: 8 Essential Steps

A properly engineered traffic control plan (TCP) reduces work zone crashes by 45% and cuts project delays by 30%, according to FHWA and Caltrans data. Rejected or incomplete plans cause 3–8 week delays and $25,000+ in penalties. Safety Network Plans, a Fresno-based PE-stamped specialist with 15 years of experience, delivers 99% first-submission approval on 1,200+ Caltrans and local agency plans annually. This step-by-step guide walks you through building a fully compliant TCP that passes review the first time. Call (559) 291-8000 or email help@safetynetworkplans.com to get your plan approved fast.

Caltrans and local agencies now require digital submissions, scaled AutoCAD drawings, and detailed phasing—DIY plans fail 68% of first reviews. Safety Network Plans uses PTV Vissim and AutoCAD Civil 3D to produce error-free plans. A Bakersfield contractor saved 28 days using our template-approved process. These eight steps meet MUTCD, Caltrans Standard Plans, and local encroachment standards.
Step 1: Gather Site Data and Traffic Volumes
Collect:

AADT, peak-hour counts, turning movements (use Caltrans PeMS or 72-hour tube counts)
Lane/shoulder widths, speed limits, sight distances
Crash history (TASAS/SWITRS)
Safety Network Plans: Provides free traffic counts and LiDAR site scans—accurate to 1 inch.

Document in title block: project limits, stationing, north arrow, scale (1"=50' typical).
Step 2: Define Project Scope and Phasing
Break work into phases:
Phase 1A – Mobilization & shoulder closure
Phase 1B – Full lane closure overnight
Rule: Never reduce capacity more than 30 minutes during peak hours.
Our Standard: Maximum 4 phases per sheet, color-coded for clarity. A Stockton overlay project used 3 phases—approved in 6 days.
Include contingency phase for weather/incidents.
Step 3: Select Proper Devices per MUTCD & CA Supplement
Table 6C-2 & Standard Plans:

PCMS: 1 mile + ½ mile + 1,000 ft advance
Channelizers: 25 ft spacing on tapers, 50 ft tangent
Arrow boards: Type C for >45 mph
Safety Network Plans: Auto-populates legend with exact MUTCD codes and quantities.

Night work = 10 fc minimum lighting + retroreflective vests (A710-1C).
Step 4: Calculate Taper Lengths and Buffer Spaces
MUTCD Formulas (mandatory):

Merging taper (≥40 mph): L = W × S
Shifting taper: L = (W × S²) / 60
Minimum 100 ft buffer before work area
Example (60 mph, 12-ft lane): Merging = 720 ft, Shifting = 480 ft
Safety Network Plans: Built-in spreadsheet stamps calculations on every sheet.

Caltrans requires formulas shown in notes—omission = automatic rejection.
Step 5: Design Pedestrian & Bicycle Detours (ADA Compliant)
Mandate: 5-ft minimum covered walkway, detectable edging, 1:20 ramps.
Bike lanes: Shift or detour with “Bike Lane Closed Ahead – Merge Left” (C30-14).
Our Plans: Include separate pedestrian phasing—passed 100% of recent reviews.
Document alternate routes with signing every 500 ft.
Step 6: Add Emergency & Contingency Plans
Required Elements:

Incident management (tow contacts, CHP notification)
Weather contingency (rain = reduce speed 10 mph, add flaggers)
24/7 on-call list
Safety Network Plans: Embeds QR code linking to live contact sheet.

Caltrans now requires this section—absence = rejection.
Step 7: Prepare Layout Sheets and Documentation
Format (11x17 or 24x36):

Title block with ENC number, PE stamp, revision table
General notes (construction hours, payment items)
Quantity table (cones, signs, AFADs)
Safety Network Plans: Delivers PDF + native DWG + signed/sealed hard copies.

Digital stamp via Bluebeam—accepted by all California agencies.
Step 8: Submit and Respond to Comments
Timeline: Submit 30–60 days before work; Caltrans review = 10–14 business days.
Pro Tip: Include cover letter summarizing impact (<500 vph = lane requirement only).
Safety Network Plans: Handles all comments—free revisions until approved.
98% of our clients mobilize on their original start date.
