Wayfinding Engineering for a 24-Hour International Land Border Crossing

Project Name: Huanggang Port

Time: 2020

Project Snapshot

Project Background

Huanggang Port is a 1,000,000 m² land border crossing connecting Shenzhen and Hong Kong. The port integrates passenger inspection, freight clearance, public transportation signage, parking facilities, border plazas, and cross-border vehicle corridors within a single transportation complex. Following the reopening of cross-border travel in February 2023, Huanggang Port resumed operation as Shenzhen’s only 24-hour passenger port.

COSUN SIGN delivered the wayfinding signage system across the restricted operational areas of the port. The project covered vehicle guidance, pedestrian navigation, inspection buildings, bus transfer areas, parking facilities, emergency evacuation routes, and temporary guidance during reconstruction. The signage system forms part of the port’s transportation infrastructure, supporting continuous traffic organization during reconstruction and daily operation.

Site & Engineering Challenges

24-Hour Operation

The port remained fully operational throughout construction. Installation work was limited to short overnight windows, typically between midnight and early morning, without interrupting customs clearance or daily traffic.

Active Roadway Installation

Large overhead traffic signs were installed above live traffic lanes serving passenger vehicles, freight trucks, and cross-border buses. Lifting operations required temporary lane control, precise scheduling, and strict safety management.

Underground Utility Constraints

Underground utilities were surveyed before foundation construction. In utility-sensitive areas, weighted foundations replaced conventional embedded foundations to avoid conflicts with existing underground infrastructure.

Multi-Trade Coordination

Signage installation was synchronized with civil works, MEP systems, intelligent transportation systems (ITS), road construction, and architectural works to match the overall construction schedule.

Engineering Strategy

Temporary First, Permanent Later

Temporary directional signs, printed barricades, modular information boards, and ground markings were installed before permanent signage became available. As construction progressed, permanent signs replaced temporary facilities in stages without interrupting navigation or traffic organization.

This phased approach accommodated changing construction layouts while avoiding repeated installation of permanent structures.

Standardized Bilingual System

All signage followed unified Chinese and English typography, international pictograms, standardized color coding, and layouts approved by customs and border authorities. The consistent information system reduced recognition time across inspection buildings, vehicle routes, and pedestrian circulation.

Modular Maintenance Design

Traffic signs and directory totems use replaceable information panels. Future updates to traffic patterns, operational requirements, or directional information can be completed by replacing the panel rather than the entire sign structure.

Materials & Engineering Specifications

Road Traffic Signs

Material

High-strength aluminum alloy or galvanized steel.

Finish

Fluorocarbon anti-corrosion coating.

Performance

HIP or Diamond Grade (DG) reflective sheeting provides long-distance visibility in both day and night conditions.

Overhead Sign Structures

Configuration

Multi-panel cantilever and gantry structures.

Purpose

Simplifies transportation, fabrication, on-site assembly, and future maintenance while accommodating large information layouts.

Directory Totems

Material

Stainless steel frame with acrylic information panels. Tempered glass protection is applied where required.

Illumination

LED edge-lighting with optical diffusion delivers uniform illumination for 24-hour readability.

Maintenance

Modular insert panels allow information updates without replacing the complete structure.

Ground Guidance

Material

Epoxy floor coating and heavy-duty PVC graphics.

Finish

Anti-slip, weather-resistant surface treatment.

Application

Precision templates and screen-printing ensure consistent alignment throughout pedestrian routes.

Structural Foundations

Foundation

Reinforced concrete where site conditions permit; weighted foundation systems in underground utility zones.

Protection

Protective bollards installed around freestanding signs.

Clearance

Minimum 5.5 m for overhead traffic signs.

Performance

Designed for wind resistance, seismic performance, corrosion resistance, and continuous 24-hour outdoor operation.

Installation & Coordination

Major installation work was completed during overnight low-traffic periods. Each work zone was opened, installed, inspected, and reopened before morning traffic resumed.

Overhead sign installation required coordination between crane operators, traffic management teams, safety supervisors, and installation crews. Construction sequences were planned in advance to minimize disruption.

Installation schedules were continuously coordinated with civil, electrical, ITS, and road contractors, allowing each signage section to be commissioned immediately after the associated infrastructure was completed.

Project Outcome

Since the full reopening of cross-border travel in February 2023, the completed signage system has supported daily vehicle and passenger circulation throughout Huanggang Port.

The system provides continuous guidance across inspection buildings, road networks, pedestrian corridors, parking facilities, and bus interchange areas. Reflective traffic signs, illuminated wayfinding, and bilingual information continue to support efficient traffic organization under 24-hour operation.

Lessons Learned

Temporary wayfinding should be engineered as part of the permanent delivery strategy rather than treated as a temporary construction measure.

The “Temporary First, Permanent Later” approach maintained continuous navigation throughout reconstruction while minimizing repeated installation work. The same methodology can be applied to airports, railway stations, ports, metro systems, and other transportation infrastructure that must remain operational during phased construction.
